Re: [SR-Users] Adding presentity_uri prefix for multi-tenanted presence/dialoginfo configuration
by Rhys Hanrahan 03 Apr '19

03 Apr '19

Hi All, I managed to solve my need to re-write NOTIFY packets with help from this thread: https://www.mail-archive.com/sr-users@lists.kamailio.org/msg08088.html This seems to work well. I am re-writing the packets as shown below… I guess my only question is, is this relatively safe/smart to do? I basically copied what our standalone Asterisk PBXes are doing in my captures, so I guess so? But I’m not confident enough to say it won’t cause some weird edge case issues. I can only say it works fine with the Snom and Yealink handsets I am testing with. I’m just concerned because it feels a bit like a hack. For SUBSCRIBE I re-write: * Request URI and To header from 101@ sent by the handset to tenant101@ (to match the SIP username of the handset - tenant101@) For NOTIFY I re-write: * From and Contact header to remove the tenant prefix, to go back to 101@ to match the BLF key configuration on the handsets. Any advice would be appreciated on if this is a bad idea, and there’s a better way. Thanks!

Like many people, I’m in the process of trying to put Kamailio in-front of Asterisk to allow it to scale out, and my plan is for Kamailio to take over registrations, usrloc and presence/dialoginfo, as we’ve had issues where handsets are failing to get BLF updates/notifys, so I am hoping a couple of Kamailio boxes can scale better in this regard. DMQ is particularly exciting in how it will allow me to build a truly distributed platform. But I’m struggling to get presence to work the way I need it to. Our environment is multi-tenanted, but we do not (and can’t really) use multi-domains. Instead, we prefix the SIP usernames with the “tenant name” such as tenanta101 and tenantb101. My problem is that all the BLFs are configured for 101@PBX with no tenant name in the User part of the URI so that internal dialing and call pickup will work. Because in Asterisk we use “subscribecontext” this hasn’t been a problem in the past – Asterisk knows for subscriptions coming from that handset that it belongs to that tenant’s context in the dialplan and they are “isolated”, so having handsets subscribe as 101@ in their request URI was never a problem. Of course, with Kamailio I don’t have subscribecontext, and my main issue is that the “presentity_uri” being stored is 101@ while each of the SIP accounts of the handsets are registered as tenenata101@, and as such, no NOTIFYs are sent by Kamailio because it thinks that there are no watchers for the presentity_uri. If I change the SIP account username to 101 to match the BLF key, NOTIFYs are sent as expected. But then this breaks call pickup and internal dialing using the BLF keys. I would rather handle this in Kamailio than in Asterisk and having to re-configure the BLF keys for hundreds of handsets. I need to do something like: * When a SUBSCRIBE comes in, I need to prefix presentity_uri with the tenant name so the subscription changes from 101@ to tenanta101@ in the active_watchers table. * When Kamailio generates a NOTIFY, the notify would be built based on presentity_uri and would come out as tenanta101@, but the phone’s BLFs are configured for 101@ so I would need to *remove* the tenant prefix before sending out the notify. Is there a good, or recommended way to handle this scenario? Maybe something entirely different to changing the presentity_uri? I’ve written the following config to re-write the request URI and To field in any incoming subscribe requests, and successfully got the active_watchers table to store a presentity_uri containing my tenant prefix. But the problem I am having is that I can’t figure out how to modify the NOTIFY packets before they are sent – and looking at cfgtrace, it seems I might not be able to? My “standard” presence + dialoginfo configuration was taken from here as a starting point: https://kb.asipto.com/kamailio:presence:k43-blf Here is what I have so far in terms of trying to make my modifications – any guidance would be greatly appreciated. It feels like there’s probably a better way to do this than re-writing critical headers like To and Request URI? @@ -466,6 +467,8 @@ request_route { # authentication route(AUTH); + route(REWRITE_PRESENCE); + # record routing for dialog forming requests (in case they are routed) # - remove preloaded route headers remove_hf("Route"); # Presence server processing route[PRESENCE] { if(!is_method("PUBLISH|SUBSCRIBE")) return; if(is_method("SUBSCRIBE") && $hdr(Event)=="message-summary") { # Asterisk is our voicemail route(TOASTERISK); # returns here if no voicemail server is configured sl_send_reply("404", "No voicemail service"); exit; } #!ifdef WITH_PRESENCE if (!t_newtran()) { sl_reply_error(); exit; } if(is_method("PUBLISH")) { handle_publish(); t_release(); } else if(is_method("SUBSCRIBE")) { # See REWRITE_PRESENCE - this should have been executed before we get here. handle_subscribe(); t_release(); } exit; #!endif +route[REWRITE_PRESENCE] { + if (is_method("SUBSCRIBE")) { + xlog("Re-writing subscribe to include tenant prefix\n"); + # The default presentity_uri needs to be prefixed with + # the tenant name + # So re-write the To header + route(TENANTINFO); + # Now grab the tenant name. + $var(subscribe_ru) = "sip:" + $var(tenant_name) + $rU + "@" + $rd; + xlog("Re-writing SUBSCRIBE To header as: $var(subscribe_ru)\n"); + insert_hf("To: $var(subscribe_ru)\r\n", "From"); + $ru = $var(subscribe_ru); + # Force change immediately: + # http://www.kamailio.org/wiki/tutorials/faq/main#why_changes_made_to_headers… + msg_apply_changes(); + } else if (is_method("NOTIFY")) { + xlog("Re-writing NOTIFY to remove tenant prefix\n"); # This code block does not get executed right now. + # We are storing the presentity_uri with a tenant prefix + # handsets do not expect this, only 101@, 102@ etc...

uac_replace_from/to, msg_apply_changes and Re-INVITE
by Henning Westerholt 03 Apr '19

03 Apr '19

Hello, I am currently debugging a strange issue related to the usage of uac_replace_from/to() after msg_apply_changes(). It works all fine, but in a Re-INVITE case it inserts the wrong headers for the 100 - Trying case. The calle side gets then a reply with wrong From/To. This happens all the time with this particular cfg. I already checked for the usual issues: - msg_apply_changes() called several times - msg_apply_changes() called after transactions created/async processing etc.. Any ideas what else could be the problem? The msg_apply_changes() is needed for some SDP filtering logic in the cfg. Thanks and regards, Henning -- Henning Westerholt - https://skalatan.de/blog/ Kamailio services - https://skalatan.de/services

Port 5060 omitted in Record-Route
by Lợi Đặng 02 Apr '19

02 Apr '19

Hi all, i was using kamailio 4.2.1 located in 2 networks > listen = tcp:MY_ADDR:5060 advertise MY_ADDR:5060 > listen = tls:MY_ADDR:5061 advertise PUBLIC_NAT_ADDR:5061 when the call made from the inside network to out side, running `record_route()` resulted in 2 Record-Route headers added (enable_double_rr=1) Record-Route: PUBLIC_NAT_ADDR:5061;transport=tls;lr > Record-Route: MY_ADDR;transport=tcp;lr That was totally fine omitting the port in the first Record-Route when using tcp (or udp) on the first realm, but when i start switching to tls, it caused trouble Record-Route: PUBLIC_NAT_ADDR:5061;transport=tls;lr > Record-Route: MY_ADDR;transport=tls;lr The client is then told to send ACK/BYE to `MY_ADDR;transport=tls` located at `MY_ADDR:5061` as per rfc3263, then the call would failed. I had another try with `record_route_preset("PUBLIC_NAT_ADDR:5061;transport=tls", "MY_ADDR:5060;transport=tls");`, it really did add what i want with explicit 5060 port on RR, `ACK/BYE` travel on the correct path, but `loose_route()` only consumes the local `Route` header (it should consume 2). So my assumption is to stick with `record_route()` function to make `loose_route()` work properly. I tried using another port on the local realm, e.g: 5062 and the port is explicitly added to the Record-Route header `MY_ADDR:5062;transport=tls;lr` So is `5060` couldn't be explicitly added to the inbound Record-Route, or i just missed something? Any help will be appreciated. P/S: I also tried 4.4.7 and it still omit my 5060 port in the RR. rgds, Loi Dang Thanh Phone : +84. 774.735.448 Email : loi.dangthanh(a)gmail.com

Compressing SIP messages
by Igor Olhovskiy 01 Apr '19

01 Apr '19

Hi! Was looking on some way to compress SIP signalling between internal servers. But found out, there are no some pre-defined or recommended mechanism of doing this. Yes, I found gzcompress module, but it will help only in case of big body, but not whole message itself. Like in some cases you can have 4-5 RR headers, which is already a lot of info. What I googled is SigComp Compact Header form As I found, SigComp is really not widely-used method and it support along opensource SIP servers/PBXes is not documented. For Compact Header form - is there any way of using Kamailio to compress message this way? Maybe also there is a way of having some intermediate proxy-layer software, that will gzip/gunzip SIP signalling in realtime? All of this actually cause info in SIP/SDP grows rapidly, unfortunately MTU size is not.

presence_dialoginfo module not sending publish on dialogue change
by Richard Nunley 01 Apr '19

01 Apr '19

To whom can be of assistance, I’m am working towards enabling presence on my Kamailio proxy but have hit a bit of a brick wall. I’m seeing dialogues being created and persisted to the database, subscriptions are being handled and rows are being written to the active_watchers table but no PUBLISH is ever being received by the server to kickoff the sending of NOTIFY to the active watchers. Further, I’m never seeing a row in the watchers table though I don’t know that this isn’t expect behavior. I’ve attached my current config for review. Any help will be greatly appreciated! Thank in advance!

Kamailio Managed Cloud
by Alex Balashov 01 Apr '19

01 Apr '19

For immediate release: ATLANTA, GA (1 April 2019)--Following its long tradition of forward-thinking innovation in open-source Real-Time Communications (RTC), the leadership of the Kamailio SIP server project (formerly known as OpenSER) has launched the Kamailio Managed Cloud (KMC). Alex Balashov of Evariste Systems and Fred Posner of The Palner Group were among several key North American stakeholders on hand to discuss it further. As Posner told us, "Kamailio Managed Cloud is a new, best-of-breed managed Kamailio hosting environment. We provide elasticity by leveraging human capital. Using our patent-pending Orchestration Turk system, our managed cloud technicians will purchase your SuperMicro bare-metal server, known as a KamBox, drive to the data centre, and rack-and-stack it on demand -- all in response to a SOAP API call! And when you want to remove your on-demand KamBox, just issue a 'delete' operation and we will decommission the hardware -- live!" "Dedicated KamBox colocation really puts the Management in Managed Cloud," emphasised Balashov. "But that doesn't mean we keep the customer out of the loop. We are using the most modern XMLHttpRequest and 'AJAX' techniques to provide a real-time dashboard with KamBox status to all users, though it will not work with Internet Explorer 6 -- we're addressing that." "Anyway, there are numerous other cloud platforms out there, many of which rely on virtualisation and automated orchestration and the like. It really takes the human touch out of the equation and gives the short shrift to quality, while also taking away jobs. And besides, how can a so-called 'virtual' machine be truly carrier-grade?" Kamailio Managed Cloud launched in two principal regions today -- US-EAST-1, located in Jacksonville, Florida, USA, and EU-CENTRAL-1, based in the booming tech hub of central Europe and birthplace of OpenSER: Berlin, Germany. Unnamed sources tell us that strategic expansion is planned for several other regions, including Flint, Michigan, USA. The mechanics of Kamailio Managed Cloud have invited questions about how other elastic cloud resources are managed, more especially elastic storage. According to KMC senior management, storage is provided via a mechanism developed by ASIPTO StorageWorks. ASIPTO chief Daniel-Constantin Mierla was on hand at the KMC launch to explain: "It's very easy. When a customer requests more space with a simple and lightweight SOAP call with just a little custom XML namespaces, then depending on the region, Fred or I receive an SMS on our smartphones from our advanced PHP backend and drive to the data centre to insert another hard drive into one of the KamBox's several drive bays. We are using the latest in advanced mobile communications, SMS, to ensure fastest response time. Of course our service level is comprehensive and includes Managed Partition Table Labelling and Managed LVM Insertion. Also there is optional Managed Filesystem Formatting for a complete portfolio of managed services. ASIPTO StorageWorks moves at the speed of global e-business. Just text us your desired filesystem layout and partitioning scheme. It is really that easy!" When asked about business focus, marketing turnaround veteran Henning Westerholt, Executive Vice President of Business Development for KMC responded: "Our target customer is a socially conscious Millennial-run corporation or start-up who see value in the unique blend of managed services and an artisanal, hand-crafted, organic approach that is compatible with social justice and takes a people-centric view." Asked to elaborate upon his vision of social justice, Westerholt added: "Virtualisation, orchestration and auto-scaling take the people out of the equation, and Kamailio is, in the end, about people, as communication in general is about people. What would it be without the people? Moreover, these mechanisms take away gainful opportunities from hard-working university graduates. Kubernetes, Docker Swarm, VMWare, and KVM contravene the social policy objective of full employment." At press time, Posner, who also heads up KMC Labs North America, was said to be lending his pioneering business vision and knack for seeing around technology trend corners to intensive work on next-generation, bleeding-edge functionality for KMC. While Posner was tight-lipped about the specifics, he did state that the 'dispatcher' module is slated to be deprecated in favour of a "human load-balancing approach to SIP requests that is both cloud-native and eco-conscious". Industry analysts agree that protocol-aware load-balancing strategies are complicated and that the application of human judgment to the problem represents a fertile field for dynamic innovation and investment. Reports from regional press confirm that KMC Labs are in the process of building a fullfilment centre for this innovative offering, said to be branded "Central Switchboard", at an undisclosed site in Bangladesh, where thousands of "Load Balance Operator" jobs have been advertised in and around the Dhaka market. -- Alex Balashov | Principal | Evariste Systems LLC Tel: +1-706-510-6800 / +1-800-250-5920 (toll-free) Web: http://www.evaristesys.com/, http://www.csrpswitch.com/

db_redis and user
by Joan Salvatella 01 Apr '19

01 Apr '19

Hello, We are working on a project that's using two active-active Kamailio 5.2 instances that redirect traffic to several Asterisk 15.4 instances. Kamailio is acting as a registrar and should store the location information of the registered terminals. The backend database is db_redis. Phone terminals get registered and the information gets looked up from the subscriber schema in redis (That's cool) but we are having problems with the locations. This is the related code: modparam("db_redis", "keys", "location=entry:ruid&usrdom:username,domain&timer:partition,keepalive") if(ds_is_from_list("1", "2", "sip:$fd:5080")) { record_route(); route(INVITE_ASTERISK); exit; } route[INVITE_ASTERISK] { xlog("L_INFO", "[R-INVITE-RESOLVER:$ci] Entering ASTERISK INVITE resolver\n"); if (!lookup("location")) { sl_send_reply("404", "User Not Found"); return; } route(INVITE_POSTROUTE); } route[INVITE_POSTROUTE] { rtpproxy_manage(); t_on_reply("MAIN_REPLY"); if(!t_relay()) sl_reply_error(); } When looking up the location schema this errors appear: 9(39) WARNING: db_redis [redis_dbase.c:1098]: db_redis_perform_query(): performing full table scan on table 'location' while performing query 9(39) WARNING: db_redis [redis_dbase.c:1101]: db_redis_perform_query(): scan key 0 is 'expires' 9(39) WARNING: db_redis [redis_dbase.c:1101]: db_redis_perform_query(): scan key 1 is 'expires' 9(39) ERROR: <core> [db_ut.c:92]: db_str2int(): Unexpected characters: [-03-29 18:16:36] 9(39) ERROR: <core> [db_val.c:76]: db_str2val(): error while converting integer value from string 9(39) ERROR: db_redis [redis_dbase.c:1062]: db_redis_convert_row(): Failed to convert redis column 'expires' to db value 9(39) ERROR: db_redis [redis_dbase.c:1231]: db_redis_perform_query(): Failed to convert redis reply for row 9(39) ERROR: db_redis [redis_dbase.c:1243]: db_redis_perform_query(): failed to perform the query 9(39) ERROR: db_redis [redis_dbase.c:1829]: db_redis_query(): failed to do the query 9(39) ERROR: usrloc [udomain.c:981]: udomain_contact_expired_cb(): db_query failed Any hints?

01 Apr '19

Hi kamailios, I meet a problem with the " kamctl alias add" command in the 5.2 version, I saw that the module used to add an alias had changed, and now the command result with an error : [kamailio]# kamctl alias add XXXX@XXXX sip:XXXXX@XXXX { "jsonrpc": "2.0", "error": { "code": 500, "message": "Not enough parameters or wrong format" }, "id": XXXXX } I read the function who return this message " static void ul_rpc_add(rpc_t* rpc, void* ctx)" in the ul_rpc.c in the usr_loc module. I tried to pass the command with two more parameters : # kamctl alias add 0175951068(a)trunk7.bornsip.fr sip:0175951068@trunk7.bornsip.fr NULL NULL { "jsonrpc": "2.0", "result": { }, "id": 29200 } And this time it works correctly, but I saw thaht the test prameters was in the field "path" , do you know why we have to indicate a path ? Are we obliged to indicate this two more parameters ? What is the utility of this field ? Thank you in advance, Igor

Lost connection to MySQL server during query

Hey Folks, Getting some annoying logs, pretty certain these are false positives. I'm running kamailio 4.4.7 using localhost mysql 5.5.60 on debian 7.11. Pretty simple setup, have acc and collecting cdrs. Relevant kamailio.cfg: loadmodule "acc.so" loadmodule "rtimer.so" loadmodule "sqlops.so" # ----- acc params ----- modparam("acc", "db_url", DBURLRW) modparam("acc", "db_flag", 1) modparam("acc", "db_missed_flag", 2) modparam("acc", "db_extra", "src_user=$fU;src_domain=$fd;src_ip=$si;" "dst_ouser=$tU;dst_user=$rU;dst_domain=$rd;" "accountcode=$avp(s:acctcode)") modparam("rtimer", "timer", "name=cdr;interval=300;mode=1;") modparam("rtimer", "exec", "timer=cdr;route=CDRS") modparam("sqlops", "sqlcon", "cb=>mysql://rwuser:rwpass@localhost/kamailio") route[CDRS] { sql_query("cb","call kamailio_cdrs()","rb"); } Logs: ERROR: db_mysql [km_dbase.c:128]: db_mysql_submit_query(): driver error on query: Lost connection to MySQL server during query (2013) ERROR: <core> [db_query.c:181]: db_do_raw_query(): error while submitting query ERROR: sqlops [sql_api.c:265]: sql_do_query(): cannot do the query [call kamailio_cdrs()] CDRs are working fine, no issues with the results, just the log messages. Errors occur every 5 minutes so this is related to the rtimer cycle, mode=1 is set for new connection so there really wouldn't be a lost connection, the old connection should have been relieved on last cycle. I've seen some other post talking about this issue but could not find any resolution or work around. Any help is appreciated. Thanks.

Hello - Is there a way I can print current timestamp in milli or microseconds in the log file? Something like: 2019-03-28 04:50:15.379 would be ideal The closest thing I could find was $TV(Sn) but it doesn't suit the purpose here since its not human readable. Thanks Pat

flags definition in kamailio.cfg + 5.2 documentation
by Joel Serrano 27 Mar '19

27 Mar '19

Hi, I saw in the Kazoo default.cfg this: ... ####### Flags ####### flags FLAG_INTERNALLY_SOURCED: 1, FLAG_ASSOCIATE_SERVER: 2, FLAG_SKIP_NAT_CORRECTION: 3, FLAG_ASSOCIATE_USER: 4, FLAG_TRUSTED_SOURCE: 5, FLAG_SESSION_PROGRESS: 6, FLAG_IS_REPLY: 7, FLAG_SIP_TRACE: 8; ... So then I went here to read about it: https://www.kamailio.org/wiki/cookbooks/5.2.x/core#flags I found out it's not documented... is this a drop-in alternative for a: #!define FLAG_NAME FLAG_BIT? Sorry, first time I see this if not I would update the docs myself... :( Thanks, Joel.

Manipulating User Agent header in dispatcher OPTIONS
by Andrew White 27 Mar '19

27 Mar '19

Hi all, I’ve set the server_header variable in my primary config, and I’ve got a catch in the default reply route to modify headers where required. I’m masking this value for security reasons, and filling it with my own value for vanity reasons :). I’ve noticed that the OPTIONS packet that is send via the dispatcher module when probing mode is on contains a User-Agent field which has the full version and OS type. Unfortunately I don’t necessarily have trust of the end destination being dispatcher to, nor the packet switchers in-between. How can I catch this OPTIONS packet to manipulate the value? It doesn’t appear to go through the REQUEST route or the ONSEND route. Thanks! ________________________________ Andrew White - Director uConnected Email: andrew(a)uconnected.com.au Web: www.uConnected.com.au

accounting and db_redis

Under https://www.kamailio.org/docs/modules/5.2.x/modules/db_redis.html#db_redis.… there is an example for using db_redis for accounting. This doesn't appear to work (5.2.2) modparam("db_redis", "keys", "acc=entry:callid,time_hires&cid:callid") results in: db_redis [redis_dbase.c:1886]: db_redis_insert(): inserting to prefix (table) 'acc' db_redis [redis_dbase.c:382]: db_redis_build_entry_keys(): build entry keys db_redis [redis_dbase.c:295]: db_redis_find_query_key(): checking for existence of ent db_redis [redis_dbase.c:306]: db_redis_find_query_key(): found key in entry key db_redis [redis_dbase.c:133]: db_redis_val2str(): converting str value '1db9c0bc57291e db_redis [redis_dbase.c:338]: db_redis_find_query_key(): entry key so far is 'acc:entr db_redis [redis_dbase.c:295]: db_redis_find_query_key(): checking for existence of entry key 'time_hires' in query db_redis [redis_dbase.c:346]: db_redis_find_query_key(): key 'time_hires' for type 'entry' not found, unable to use this type db_redis [redis_dbase.c:405]: db_redis_build_entry_keys(): Failed to create direct entry key, no matching key definition db_redis [redis_dbase.c:1892]: db_redis_insert(): failed to build entry keys db_redis [redis_dbase.c:1976]: db_redis_insert(): failed to do the insert What does work is "time" instead of "time_hires". Since I have no idea what values are available (I guess the table names?) and time only has a 1 sec resolution, what is a correct version of time_hires?

DBText does not exists!
by Andrew White 27 Mar '19

27 Mar '19

Hi all, I’m currently playing with the UAC module to hand off remote registrations with trunks to Kamailio. I want to keep Kamailio’s external connections low, so I’m planning to use db_text to load the UAC info, and populate the flat file via other methods. When attempting to load my UAC DB via db_text however, I get the following: Mar 26 04:59:30 ip-10-0-0-2 /usr/local/sbin/kamailio[31904]: ERROR: db_text [dbt_lib.c:143]: dbt_cache_get_db(): database [/etc/kamailio/uac.db] does not exists!

Extract URI from Headers
by Duarte Rocha 27 Mar '19

27 Mar '19

Greetings, In my SBC i usually have to do operations on P-Asserted-Identity and Contact header. For those operations i usually have to get the user part, domain, etc. For that i'm using the URI Transformations provided by Kamailio. However, in order to do this i have to trim the header value by hand in order to remove brackets, display infos, etc. Does Kamailio have a method for extracting the URI from those kinds of headers? Best Regards, Duarte Rocha

Disable Dispatcher GW from DB
by Patrick Wakano 26 Mar '19

26 Mar '19

Hello list, Hope you are all doing well! I am looking for a way to disable a Dispatcher GW from the DB. I know I can disable it using the "kamcmd dispatcher.set_state d ..."command, but in case I do a reload or restart after that, the disabled GW will be back as active. Of course I could also delete the GW from DB, but for CDR purposes I want to keep the entry but mark as permanently disabled, so Kamailio won't try to use it nor ping it anymore. Does anyone how can I do that in the DB? I am looking for the exact same behavior the "kamcmd dispatcher.set_state d" does but from some change in the DB. Thanks, Kind regards, Patrick Wakano

Presence module. How to update contact DB record after re-SUBSCRIBE ?

Hello! We are using Presence module with MySQL with parameters below. And looks like module does not update contact DB record in case of re-SUBSCRIBE.

Adding presentity_uri prefix for multi-tenanted presence/dialoginfo configuration
by Rhys Hanrahan 26 Mar '19

26 Mar '19

Hi Everyone, I’ve recently just started working with Kamailio – thanks everyone for this amazing software. Like many people, I’m in the process of trying to put Kamailio in-front of Asterisk to allow it to scale out, and my plan is for Kamailio to take over registrations, usrloc and presence/dialoginfo, as we’ve had issues where handsets are failing to get BLF updates/notifys, so I am hoping a couple of Kamailio boxes can scale better in this regard. DMQ is particularly exciting in how it will allow me to build a truly distributed platform. But I’m struggling to get presence to work the way I need it to. Our environment is multi-tenanted, but we do not (and can’t really) use multi-domains. Instead, we prefix the SIP usernames with the “tenant name” such as tenanta101 and tenantb101. My problem is that all the BLFs are configured for 101@PBX with no tenant name in the User part of the URI so that internal dialing and call pickup will work. Because in Asterisk we use “subscribecontext” this hasn’t been a problem in the past – Asterisk knows for subscriptions coming from that handset that it belongs to that tenant’s context in the dialplan and they are “isolated”, so having handsets subscribe as 101@ in their request URI was never a problem. Of course, with Kamailio I don’t have subscribecontext, and my main issue is that the “presentity_uri” being stored is 101@ while each of the SIP accounts of the handsets are registered as tenenata101@, and as such, no NOTIFYs are sent by Kamailio because it thinks that there are no watchers for the presentity_uri. If I change the SIP account username to 101 to match the BLF key, NOTIFYs are sent as expected. But then this breaks call pickup and internal dialing using the BLF keys. I would rather handle this in Kamailio than in Asterisk and having to re-configure the BLF keys for hundreds of handsets. I need to do something like: * When a SUBSCRIBE comes in, I need to prefix presentity_uri with the tenant name so the subscription changes from 101@ to tenanta101@ in the active_watchers table. * When Kamailio generates a NOTIFY, the notify would be built based on presentity_uri and would come out as tenanta101@, but the phone’s BLFs are configured for 101@ so I would need to *remove* the tenant prefix before sending out the notify. Is there a good, or recommended way to handle this scenario? Maybe something entirely different to changing the presentity_uri? I’ve written the following config to re-write the request URI and To field in any incoming subscribe requests, and successfully got the active_watchers table to store a presentity_uri containing my tenant prefix. But the problem I am having is that I can’t figure out how to modify the NOTIFY packets before they are sent – and looking at cfgtrace, it seems I might not be able to? My “standard” presence + dialoginfo configuration was taken from here as a starting point: https://kb.asipto.com/kamailio:presence:k43-blf Here is what I have so far in terms of trying to make my modifications – any guidance would be greatly appreciated. It feels like there’s probably a better way to do this than re-writing critical headers like To and Request URI? @@ -466,6 +467,8 @@ request_route { # authentication route(AUTH); + route(REWRITE_PRESENCE); + # record routing for dialog forming requests (in case they are routed) # - remove preloaded route headers remove_hf("Route"); # Presence server processing route[PRESENCE] { if(!is_method("PUBLISH|SUBSCRIBE")) return; if(is_method("SUBSCRIBE") && $hdr(Event)=="message-summary") { # Asterisk is our voicemail route(TOASTERISK); # returns here if no voicemail server is configured sl_send_reply("404", "No voicemail service"); exit; } #!ifdef WITH_PRESENCE if (!t_newtran()) { sl_reply_error(); exit; } if(is_method("PUBLISH")) { handle_publish(); t_release(); } else if(is_method("SUBSCRIBE")) { # See REWRITE_PRESENCE - this should have been executed before we get here. handle_subscribe(); t_release(); } exit; #!endif +route[REWRITE_PRESENCE] { + if (is_method("SUBSCRIBE")) { + xlog("Re-writing subscribe to include tenant prefix\n"); + # The default presentity_uri needs to be prefixed with + # the tenant name + # So re-write the To header + route(TENANTINFO); + # Now grab the tenant name. + $var(subscribe_ru) = "sip:" + $var(tenant_name) + $rU + "@" + $rd; + xlog("Re-writing SUBSCRIBE To header as: $var(subscribe_ru)\n"); + insert_hf("To: $var(subscribe_ru)\r\n", "From"); + $ru = $var(subscribe_ru); + # Force change immediately: + # http://www.kamailio.org/wiki/tutorials/faq/main#why_changes_made_to_headers… + msg_apply_changes(); + } else if (is_method("NOTIFY")) { + xlog("Re-writing NOTIFY to remove tenant prefix\n"); # This code block does not get executed right now. + # We are storing the presentity_uri with a tenant prefix + # handsets do not expect this, only 101@, 102@ etc...

Default port interference in TLS conneciton
by Dalibor Zeman 24 Mar '19

24 Mar '19

Hello, I am running Kamailio v. 5.1.2 with typical configuration for wss connections (default config + tls, websocket, nathelper modules), quite everything is running as should, but I am quite concerned about what I got on Homer server. My Kamailio is listening on port 4443 for TLS. Opening dialog runs as should, then UPDATE and BYE messages are received on 4443, but sent out on 5060. When I don't set up default port, 403 reply comes on a call. I'd like to know whether it is something defined by standard or it has a meaning and I should leave it as it is, or I should correct it somehow and then how. Also, if it has a meaning, then what it is. Thanks for your answer, Dalibor Zeman.

KEMI Ruby - exit from within function
by Andrew White 23 Mar '19

23 Mar '19

Hi all, I know ruby is pretty new to KEMI, so I understand this might not be supported. I’ve been able to build a functional basic configuration using KEMI based app_ruby. However the function KSR::x.exit is not exposed to the interpreter. Reading up on the function (https://kamailio.org/docs/tutorials/devel/kamailio-kemi-framework/kemimods/… <https://kamailio.org/docs/tutorials/devel/kamailio-kemi-framework/kemimods/…>) I can see either a native `exit` or a return from the request_route is recommended. The latter of these works fine, however the former throws the following error when called either within the request_route function or any others: Mar 22 03:40:46 guest /usr/sbin/kamailio[17474]: ERROR: {1 19731 BYE 8u6We4ReU01GuU-zoa7VuqC.qWwwg29S} app_ruby [app_ruby_api.c:105]: app_ruby_print_last_exception(): exception: exit Mar 22 03:40:46 guest /usr/sbin/kamailio[17474]: ERROR: {1 19731 BYE 8u6We4ReU01GuU-zoa7VuqC.qWwwg29S} app_ruby [app_ruby_api.c:1078]: app_ruby_run_ex(): ruby exception (6) on callback for: ksr_request_route (res type: 17) It appears the app_ruby wrapper is seeing an exit as an exception and throwing an error. I’m unsure if this is affecting my actual flow (still building the config), but the error in the logs is certainly annoying. Returning from the request_route function works fine, however this is obviously harder to do from within a sub function. Any direction on how to correctly exit in similar ways to native or other KEMI implementations would be appreciated. By the way, thanks Daniel for writing this module! This makes Kamailio significantly more accessible for myself and others like me! ________________________________ Andrew White - Director uConnected Email: andrew(a)uconnected.com.au Web: www.uConnected.com.au

Kamailio initial log - Mysql error

Hi, I am new at Kamailio, I have installed a vicidial goautodial box and having some headaches. I can see at starup logs the following message: Mar 18 02:12:34 edialer1 /usr/sbin/kamailio[4028]: ERROR: db_mysql [km_my_con.c:129]: db_mysql_new_connection(): driver error: Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2 "No such file or directory") Mar 18 02:12:34 edialer1 /usr/sbin/kamailio[4028]: ERROR: <core> [db.c:318]: db_do_init2(): could not add connection to the pool Mar 18 02:12:34 edialer1 /usr/sbin/kamailio[4028]: ERROR: usrloc [dlist.c:654]: register_udomain(): failed to open database connection However if I execute the following command: [root@edialer1 kamailio]# kamctl db show subscriber database engine 'MYSQL' loaded Control engine 'RPCFIFO' loaded +----+------------+----------------------------+----------+---------------+- ---------------------------------+----------------------------------+------+ | id | username | domain | password | email_address | ha1 | ha1b | rpid | +----+------------+----------------------------+----------+---------------+- ---------------------------------+----------------------------------+------+ | 18 | 5474470533 | vaglxc01.goautodial.com | | NULL | 10685ad93a251bb460e7dd544a174288 | 1680d2aebe5f750c4eedb45ad6b5ba4f | NULL | | 20 | 5505791853 | edialer1.gevolution.com.br | | NULL | 04e377e3923716fb5038b0caa79b8ed3 | d65362c7ccd934f00efa21c45e479ec5 | NULL | | 21 | 2347600834 | edialer1.gevolution.com.br | | NULL | 065fc461faa06cec682213cf17352630 | 4d79bc7db16f74d13d1785dafb30391c | NULL | +----+------------+----------------------------+----------+---------------+- ---------------------------------+----------------------------------+------+ I get a DB response.so is Kamailio actually connected to the db or not?

Why I am not sure? Because can't see any information on it sending information to asterisk listening on port 5070, logs won't show such action. As I can't find the asterisk information at the kamailio.cfg file, I assume it is stored at the DB, and if DB connection is broken, would explain why it doesn't work. Can you please help me to figure this out? Thanks in advance

How fair is the rtpengine loadbalancing?
by Daniel Tryba 22 Mar '19

22 Mar '19

I have 3 rtp backends defined with equal weights (33 each). But when I look at the number of calls being handled the spreaded load is always 5:4:3 for the machines in the orderd listed: modparam("rtpengine", "rtpengine_sock", "udp:10.235.32.60:7723=33 udp:10.235.32.59:7723=33 udp:10.235.32.58:7723=33") Looking at select_rtpp_node_new I see nothing unfair happening (with my total lack of knowledge of how the node set is populated). Anybody else noticing this?

Auth for SUBSCRIBE and others
by Kevin Olbrich 22 Mar '19

22 Mar '19

Hi! I am implementing forwarding of SUBSCRIBE (BLF) to an Asterisk behind Kamailio. This works but Kamailio is not requesting for Auth. I then added SUBSCRIBE to: https://github.com/kamailio/kamailio/blob/master/etc/kamailio.cfg#L746 And it now challenges the client correctly. Why does this line only show REGISTER? Shouldn't it request a challenge for all messages? And why does it work with INVITES ootb? Thank you! Kind regards Kevin

How can one change acc table name in Kamailio.cfg
by Z 22 Mar '19

22 Mar '19

For some reason these two modparams are always ignored. The table name used is always acc which is default name. How can I change the table name? loadmodule "acc.so" modparam("acc", "db_table_acc", "*acc_$time(year)_$time(mon)*") modparam("acc", "db_table_missed_calls", "*acc_$time(year)_$time(mon)*") Accounting works as expected otherwise. Appreciate any help. Thanks.

Re: [SR-Users] Problem at Rx Interface - kamailio P-CSCF 5.1.6
by Valentin Christoph 20 Mar '19

20 Mar '19

Hi all, Remember this question from 23.1. It's solved now, thanks for help:-) All the best Christoph Von meinem Samsung Galaxy Smartphone gesendet. -------- Ursprüngliche Nachricht -------- Von: Valentin Christoph <Christoph.Valentin(a)kapsch.net> Datum: 23.01.19 15:06 (GMT+01:00) An: sr-users(a)lists.sip-router.org Cc: Scherney Theodor <Theodor.Scherney(a)kapsch.net>, Onic Roman <Roman.Onic(a)kapsch.net> Betreff: [SR-Users] Problem at Rx Interface - kamailio P-CSCF 5.1.6 Hi all, We are using kamailio 5.1.6, configured as P-CSCF, facing following problem. Please indicate, if you need further information – e.g. I could provide a tshark trace. If during call setup (by simulated UAs) at the terminating P-CSCF the simulated PCRF rejects the Diameter AAR message, then the kamailio P-CSCF runs into a questionable behaviour. By calling the Rx_AAR() function in configuration, the processing of the 200 OK is suspended (by the ims_qos module) and then resumed with the receipt of the AAA message. Now the ims_dialog module is called with the dlg_terminate(“all”, “reason”) function, but the 200 OK has not yet been sent. The ims_dialog sends CANCEL downstream and 488 upstream. However, the 200 OK is sent additionally. We would rather have expected the ims_dialog module should send BYE in both directions. When we respond the CANCEL with 481 Call/Transaction does not exist (which we MUST according to RFC 3261), then we would expect the ims_dialog module at least now to react with BYE in both directions. Could you help? What’s our misunderstanding? How could we proceed to get this issue fixed?

IMS: ims_isc, ims_registrar_scscf: some additions for 3rd party registration
by Valentin Christoph 20 Mar '19

20 Mar '19

Dear all, Dear Daniel, We had implemented a few additions for third party registration, based on kamailio 5.1.0 IMS modules. * either service info OR original REGISTER request or original 200 OK can be added as body to the 3rd party Registration Request, if indicated by the HSS in the user data * change: S-CSCF does not check for TEL URI, before it sends P-Associated URI to AS (SIP URIs are also sent) We would like to provide a pull request within the next days or week to have the changes as basis for a change in release 5.3.x. Drawback: probably our solution would need to be slightly modified, because we removed the check for TEL URI, if the S-CSCF sends the P-Associated-URI header to the AS in the 3rd party register request (maybe introduce a module parameter?). Any comments? Would it be reviewed and maybe taken for 5.3?

event_route tm:branch-failure and onreply_route shared variables
by Володимир Іванець 20 Mar '19

20 Mar '19

Hello! I have Kamailio setup with registrar configured to allow multiple registrations. *branch_route[MANAGE_BRANCH]* contains *t_on_reply("REPLY")* and *t_on_branch_failure("FAILURE")*. *event_route[tm:branch-failure:FAILURE]* is used to do some logic, store information in htable and in the end it calls *t_relay* function. This creates new branch. Replies for this branch go to* onreply_route[REPLY]*. The problem is that I can not find appropriate variable that would be available in both *event_route tm:branch-failure* and *onreply_route*. I need it to get saved data from htable. $T_reply_ruid is available in first one but not in second. $T_branch_idx obviously changes so it can not be used. Some registrations do not have *Received* value so source IP address and ports can not be used. *Address* value can be compared with *Contact* header from responce tacket but it is so long that it looks like it's not optimal way to do. What interesting is that $T_reply_ruid is accessible in original replies for branches that have not failed. Does anyone know what variable can be used in this case or how to make sure that $T_reply_ruid will be set? Thanks a lot!

Pseudo-Variable {$au} is NULL
by Daniel Meyer-Wendt 20 Mar '19

20 Mar '19

Hi All, I am updating our Kamailio from 4.0.6 to the latest 5.2.2, we use kamailio as LB in front of two asterisk server. My problem is that during registration forward to the asterisk servers {$au} is NULL This is the code we have, which is the one you find in most documentations $uac_req(furi)="sip:" + $au + "@" + $var(rip); I logged some Pseudo-Variable to see their contents: {$au} NULL {$aU} NULL {$Au} username(a)domain.com {$fU} username {$oU} NULL {$ru} rU: {sip:domain.com;transport=UDP and ended up doing this which works $uac_req(furi)="sip:" + $fU + "@" + $var(rip); Any idea what could be wrong? Thanks, Daniel

Kamailio books
by Kevin Olbrich 20 Mar '19

20 Mar '19

Hi! Are there any Kamailio books? I am still struggling with Kamailio on scenarios that need more then REGISTER-offloading (like Kamailio cluster with BLF, custom NOTIFY, DMQ, etc.). Online docs are very limited or use Kamailio as a single tenant PBX. What I need is a high available and high performance proxy in front of asterisk, capable of handling thousands of tenants (each with BLF working). I am perfectly fine with building a solution for several months but I am still unable to understand everything from the docs. Where do the PROs and service companies get their knowledge from? Kind regards Kevin

Kamailio crashing and infinite-looping when trying to free memory
by Enrico Bandiera 19 Mar '19

19 Mar '19

Hi guys, recently we had some issues with kamailio in production, a proxy at the edge of the infrastructure was crashing seemingly randomly, it happened a couple of times in a timespan of 4-5 days until a point where we found it in an endless loop, unable to process SIP packets anymore and printing in loop messages like these: 50(60) CRITICAL: <core> [core/mem/q_malloc.c:512]: qm_free(): BUG: freeing already freed pointer (0x7ff40a359450), called from core: core/usr_avp.c: destroy_avp_list_unsafe(626), first free core: core/usr_avp.c: destroy_avp_list_unsafe(626) - ignoring 50(60) CRITICAL: <core> [core/mem/q_malloc.c:512]: qm_free(): BUG: freeing already freed pointer (0x7ff409c4fa58), called from core: core/usr_avp.c: destroy_avp_list_unsafe(626), first free core: core/usr_avp.c: destroy_avp_list_unsafe(626) - ignoring We managed to replicate the crash and the loop in a dev environment with a lot of difficulties. It seems not related to the peak load, but to the growing number of processed calls The kamailio version is: version: kamailio 5.2.2 (x86_64/linux) flags: STATS: Off, USE_TCP, USE_TLS, USE_SCTP, TLS_HOOKS, USE_RAW_SOCKS, DISABLE_NAGLE, USE_MCAST, DNS_IP_HACK, SHM_MEM, SHM_MMAP, PKG_MALLOC, Q_MALLOC, F_MALLOC, TLSF_MALLOC, DBG_SR_MEMORY, USE_FUTEX, FAST_LOCK-ADAPTIVE_WAIT, USE_DNS_CACHE, USE_DNS_FAILOVER, USE_NAPTR, USE_DST_BLACKLIST, HAVE_RESOLV_RES ADAPTIVE_WAIT_LOOPS=1024, MAX_RECV_BUFFER_SIZE 262144 MAX_URI_SIZE 1024, BUF_SIZE 65535, DEFAULT PKG_SIZE 8MB poll method support: poll, epoll_lt, epoll_et, sigio_rt, select. id: unknown compiled with gcc 5.3.1 Every time this happened it was the timer pid that was crashing or looping, we managed to get 2 core dumps of the crash and 1 of the loop (got it after killing the timer with SIGQUIT). The timer process crashes after attempting to free memory that it's not correctly managed. In particular we saw that it happens inside destroy_avp_list_unsafe() called by the tm timer, when uri_avps_from points to an invalid memory address. We don't use dialog, uac, http_async_client, but we do use topos. In the crash dumps it seems that there's something wrong inside free_cell_helper(), when trying to clean the dead_cell something goes wrong while freeing uri_avps_from, here's the crash log: 61(76) CRITICAL: <core> [core/pass_fd.c:277]: receive_fd(): EOF on 66 0(15) ALERT: <core> [main.c:740]: handle_sigs(): child process 65 exited by a signal 11 0(15) ALERT: <core> [main.c:743]: handle_sigs(): core was generated 0(15) INFO: <core> [main.c:766]: handle_sigs(): terminating due to SIGCHLD <childs getting the SIGTERM signal> 0(15) CRITICAL: <core> [core/mem/q_malloc.c:512]: qm_free(): BUG: freeing already freed pointer (0x7f4d60a2e168), called from htable: ht_api.c: ht_cell_free(217), first free core: core/usr_avp.c: destroy_avp_list_unsafe(626) - ignoring 0(15) INFO: <core> [core/sctp_core.c:53]: sctp_core_destroy(): SCTP API not initialized Before the crash we have no warnings on errors about shared memory allocation backtrace: (gdb) bt full #0 0x00000000006371d7 in destroy_avp_list_unsafe (list=0x7f34f7a411b0) at core/usr_avp.c:625 avp = 0x2 foo = 0x2 __func__ = "destroy_avp_list_unsafe" #1 0x00007f351c6909ab in free_cell_helper (dead_cell=0x7f34f7a41018, silent=0, fname=0x7f351c796a02 "timer.c", fline=689) at h_table.c:260 b = 0x0 i = 1 rpl = 0x0 tt = 0x0 foo = 0x11c68daf2 cbs = 0x0 cbs_tmp = 0x7f34f80c3790 __func__ = "free_cell_helper" #2 0x00007f351c7291e6 in wait_handler (ti=1984410416, wait_tl=0x7f34f7a410a0, data=0x7f34f7a41018) at timer.c:689 p_cell = 0x7f34f7a41018 ret = 1 unlinked = 0 rcount = 1 __func__ = "wait_handler" #3 0x00000000004d0f56 in timer_list_expire (t=1984410416, h=0x7f34f6be7850, slow_l=0x7f34f6bea368, slow_mark=2702) at core/timer.c:874 tl = 0x7f34f7a410a0 ret = 0 #4 0x00000000004d13bd in timer_handler () at core/timer.c:939 saved_ticks = 1984410416 run_slow_timer = 0 i = 654 __func__ = "timer_handler" #5 0x00000000004d1845 in timer_main () at core/timer.c:978 No locals. #6 0x0000000000425cc8 in main_loop () at main.c:1727 i = 8 pid = 0 si = 0x0 si_desc = "udp receiver child=7 sock=127.0.0.1:5060 \000\000\000\000q\000\000\000@6y\000\000\000\000\000\000\b\206|\210X\322:\032\301\255\000\000\000\000\000\000\000\000 \000\000\000\000\000\000\000\002\000\000\000\000\063\275{\000\000\000\000\000>", '\000' <repeats 15 times>, "\320\220\377\226\374\177\000\000\351\022a\000\000\000\000" nrprocs = 8 woneinit = 1 __func__ = "main_loop" #7 0x000000000042ca76 in main (argc=10, argv=0x7ffc96ff9398) at main.c:2696 cfg_stream = 0x25ca010 c = -1 r = 0 tmp = 0x7ffc96ffa4c9 "" tmp_len = -1761635728 port = 32764 proto = -1761635632 options = 0x76c598 ":f:cm:M:dVIhEeb:l:L:n:vKrRDTN:W:w:t:u:g:P:G:SQ:O:a:A:x:X:Y:" ret = -1 seed = 1492539644 rfd = 4 debug_save = 0 debug_flag = 0 dont_fork_cnt = 2 n_lst = 0x7f351f6f6718 p = 0xffffffff <error: Cannot access memory at address 0xffffffff> st = {st_dev = 2049, st_ino = 1282695, st_nlink = 2, st_mode = 16895, st_uid = 0, st_gid = 0, __pad0 = 0, st_rdev = 0, st_size = 4096, st_blksize = 4096, st_blocks = 8, st_atim = {tv_sec = 1552931478, tv_nsec = 972761643}, st_mtim = {tv_sec = 1552931478, tv_nsec = 972761643}, st_ctim = {tv_sec = 1552931478, tv_nsec = 972761643}, __glibc_reserved = {0, 0, 0}} __func__ = "main" In the loop dump we have a different situation, there's a loop in the uri_avps_from structure as you can see from the next pointers: (gdb) p *dead_cell->uri_avps_from $3 = {id = 66, flags = 275, next = 0x7ff40a359450, d = {p = 0x7ff40a9ad540, l = 140686126667072, data = "@\325\232\n\364\177\000"}} (gdb) p *dead_cell->uri_avps_from.next $4 = {id = 66, flags = 275, next = 0x7ff409c4fa58, d = {p = 0x7ff40a359480, l = 140686120031360, data = "\200\224\065\n\364\177\000"}} (gdb) p *dead_cell->uri_avps_from.next.next $5 = {id = 66, flags = 275, next = 0x7ff40a359450, d = {p = 0x7ff409c4fa88, l = 140686112651912, data = "\210\372\304\t\364\177\000"}} backtrace: (gdb) bt full #0 0x00007ff43152e67e in _IO_default_xsputn () from /lib/x86_64-linux-gnu/libc.so.6 No symbol table info available. #1 0x00007ff43150150b in vfprintf () from /lib/x86_64-linux-gnu/libc.so.6 No symbol table info available. #2 0x00007ff431502ef1 in ??
