Hello dear list, I am looking for a tool that will provide me call statistics (ASR and ACD) by destination/country with alerting by emails. I try to detect when a sip provider does not work well in order to route the traffic to another sip provider. Thank you. Abdoul OSSENI AfriCallShop

Re: [SR-Users] How to determine correct port to set in record-route header

Any help?

180 and 183 SIP messages
by Ali Taher 30 Mar '18

30 Mar '18

Hello everyone, I'm working on freeswitch , where I have SIP calls coming from A-Party to my freeswitch and I'm routing it to B-Party. I'm facing an issue , when I'm getting back the 183 message from the supplier(B-Party) and forwarding it to the customer(A-Party); the customer is not hearing the RBT and asking to send 180 rather than 183 . (the supplier is only sending 183 without 180). Is it possible using kamailio to replace this 183 message with 180 message , or even add 180 message while keeping the same 183 message ? Regards, Ali Taher

kamailio & vmware
by Jean Cérien 29 Mar '18

29 Mar '18

Hello We are running a kamailio 5.0 on a VMWARE / VSPHERE 6.0 vm, with a couple of asterisk running on 2 physical hosts. Audio goes straight to the asterisk, no rtpengine / rtpproxy. I actually have no audio issues, but communication between the asterisk & kamailio for sip sometime fails - I get a few 408. I cant tell if this is network related or virtualisation related. Anyone has advice on kamailio on a VM, when it only handles sip ? Rgds J.

Kamailio to Asterisk Proxy with NAT
by Benjamin Marty 29 Mar '18

29 Mar '18

Hello, I have multiple Asterisk Servers in a private Network. They also have a Public IP via Destination NAT. Now I want to use a Kamailio Proxy in front of them. The Routing I want to do with the Kamailio Dispatcher module. My Question is now how the RTP Media Stream should/can flow. The clients are in different other networks. So P2P Media Stream isn't possible. Should I now run the RTP Stream Client - Asterisk or Client - Kamailio - Asterisk? Is there an Example for an such scenario? Thanks Benjamin

Kamailio NAT AWS EC2
by Benjamin Marty 29 Mar '18

29 Mar '18

Hi, I am new to Kamailio and coming a bit from the Asterisk side. My goal is to set up a bunch of users on a Kamailio Instance on AWS EC2 and get them able to call each other and talk to each other over the Internet without P2P media stream. Is rtpproxy the tool that enables that? As far my knowledge is right Kamailio isn't able to do any sort of RTP handling. Regards, Benjamin

is t_flush_flags() really needed?
by Juha Heinanen 28 Mar '18

28 Mar '18

While testing xflags, i noticed that a regular flag that I set AFTER calling t_newtrans() stays set in onreply_route even when I do not call t_flush_flags(). In a route block: if (!t_newtran()) { ERROR(Failed to create new transaction for $rm <$ru>); exit; }; if (!isflagset(19)) INFO(******** flag 19 is NOT set after t_newtran()); setflag(19); and in onreply_route: if (isflagset(19)) INFO(********* flag 19 is set); else INFO(********* flag 19 is NOT set); Syslog gets: Mar 25 11:24:41 trout /usr/bin/sip-proxy[21362]: INFO: ******** flag 19 is NOT set after t_newtran() Mar 25 11:24:41 trout /usr/bin/sip-proxy[21433]: INFO: ********* flag 19 is set So what is the point of t_flush_flags()? -- Juha

Terminate dialog from another dialog
by Joel Serrano 27 Mar '18

27 Mar '18

Hi guys, I'm trying to set kamailio to not allow simultaneous calls from the same user, but if a second call comes in, the behavior desired is to process that second call and terminate the previous (already active) one. Say you have call A that creates dialog A. Then you have call B come in, creates dialog B. Can I save some info from dialog (call) A in a htable for example, then check that htable for the needed info from dialog (call) B and terminate dialog (call) A if it exists? I think using dlg_get() and dlg_bye() would do the trick but not 100% sure how they work.. The example in the docs seems exactly the case: dlg_get --> "Search and set current dialog based on Call-ID, From-Tag and To-Tag parameters" if(dlg_get("abcdef", "123", "456")) { dlg_bye("all"); } After the dlg_get() and dlg_bye() what happens to call B? Does the route continue running or does it end? Will it automatically switch back to the current dialog or do you have to manually switch back running dlg_get() again? (Sorry if I'm not explaining myself correctly, let me know if it sounds confusing) Does anyone have experience with these two functions? Thanks, Joel.

To tags in 407 challenges
by Alex Balashov 27 Mar '18

27 Mar '18

Hi, This may be more a SIP question than a Kamailio question, but I am trying to figure out why 407 challenges from Kamailio contain To tags. I suppose I've not run across it before, and I can't find an RFC-based rationale. A negative reply to an invite transaction without an intermediate early dialog-forming reply (e.g. 183 with To tag) does not form a dialog, nor takes place within a context in which a dialog was created. So what gives? Insights appreciated! -- Alex -- 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/

Hi all, anyone try the evrexec module yet? When I try, Kamailio fails to start and I'm getting an error that it can't find the event route I'm specifying in the modparam, but I started with trying the example from the docs. I think it might be a bug https://www.kamailio.org/docs/modules/5.1.x/modules/evrexec.html Here's what I tried: modparam("evrexec", "exec", "name=evrexec:timer;wait=1000;workers=1;") event_route[evrexec:timer] { $var(x) = 0; while(1) { xlog("$$var(x) is $var(x)\n"); $var(x) = $var(x) + 1; sleep("600"); } } Here's the log: 0(1765) ERROR: evrexec [evrexec_mod.c:232]: evrexec_param(): event route not found: evrexec:timer 0(1765) CRITICAL: <core> [core/cfg.y:3450]: yyerror_at(): parse error in config file /etc/kamailio/kamailio.cfg, line 136, column 70: Can't set module parameter ERROR: bad config file (1 errors) Version info: kamailio -V version: kamailio 5.1.2 (x86_64/linux) flags: STATS: Off, USE_TCP, USE_TLS, USE_SCTP, TLS_HOOKS, 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_LISTEN 16, 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 on 06:41:34 Mar 9 2018 with gcc 4.8.5 Thoughts?

Dispatcher Routing Failure
by Daniel W. Graham 27 Mar '18

27 Mar '18

What constitutes a 'failed request' in dispatcher module, in which a gateway is marked inactive? >From documentation - ds_ping_interval With this parameter you can define the interval for sending a request to a gateway marked as inactive upon a failed request routing to it. ds_probing_threshold If you want to set a gateway into inactive mode, there can be a specific number of failed requests until it will change from "active" to "inactive".

Regular Expression Syntax
by Duarte Rocha 27 Mar '18

27 Mar '18

Greetings, I'm having some trouble with the syntax used in the {re.subst,expression} method. What i want to do is add a prefix to a capture group. I can make it work like that /^[0-9]+/prefix$tU/ but this solution is far from perfect since i may not need the entire $tU. I would like to use it like this /^[0-9]+/prefix\1/ in order to not limit my regex to Kamailio only. When i do it like this the regex result is only "prefix". What's the correct syntax to add a prefix using the capture group ? Thanks in advance

topos_redis and session-timer timeouts

Kamailio Call monitoring
by Tomi Hakkarainen 27 Mar '18

27 Mar '18

Hi you all, I have set up Kamailio and RTPProxy in front of Asterisk. Currently successfully able to route calls from two differrent SIP-Trunk providers terminated to Kamailio and RTPProxy. I would like to get a view of calls currently running through Kamailio? I should be able to see some details about the call like the calling called numbers and the time call has been active. I’m not sure if Siremis would provide such view. Also looked Homer and also not sure it has something like that. Still those provide much more like for troubleshooting. If anyone has idea how that would be possible to accomplish or know that there already is such implementation I would be interested. Tomi

Kamailio NAT AWS EC2
by Ilie Soltanici 27 Mar '18

27 Mar '18

Hi, First of all, check if SIP Traffic is going through your SIP Server, not directly between Endpoints. To do this check if Record-route parameter is set in configuration file: record_route(); https://www.kamailio.org/docs/modules/5.1.x/modules/rr.html Also, be sure that in SDP body you have External IP of your Kamailio/RTPproxy. If Kamailio is behind NAT you may need to use fix_nated_sdp function from nathelper module: https://www.kamailio.org/docs/modules/5.1.x/modules/nathelper.html#nathelpe… Regards,

Hello, I use kamailio 5.1.1 with default configuration for PRESENCE: Route: #!ifdef WITH_PRESENCE if (!t_newtran()) { sl_reply_error(); exit; } if(is_method("PUBLISH")) { handle_publish(); t_release(); } else if(is_method("SUBSCRIBE")) { handle_subscribe(); t_release(); } exit; #!endif and modparams: #!ifdef WITH_PRESENCE # ----- presence params ----- modparam("presence", "db_url", DBURL) # ----- presence_xml params ----- modparam("presence_xml", "db_url", DBURL) modparam("presence_xml", "force_active", 1) #!endif I use and GRANSTREAM phones. When I make subscribe from soft sip client (Micro sip) to the grandstreams, all NOTIFY messages are without XML. Subscriptions between two soft sip clients like Zoiper and Micro SIP works perfectly. Is this related to GRANDSTREAM phones - configuration or so... or is necessary to modify kamailio configuration and if Yes, please provide some hitns how to change kamailio config? Thanks in advance. Best regards.

Strange auth_challenge behaivor on 407
by Yuriy Gorlichenko 27 Mar '18

27 Mar '18

Hi I'm using version: kamailio 5.1.2 I have strange issue with auth_challenge kamialio works as NAT handler. When Register comes kamailio handles nat and save original ip:port at the received field in location table I found that when local port in contact is different than external port reply 407 on INVITE comes to externalip (from received) : internalport(from contact) And never reaches destination for exmaple Register comes from 192.168.1.10:50555 Kamailio saves at the Received 12.1.1.12:1030 but when invite comes form 12.1.1.12:1030 kamailio sends reply to 12.1.1.12:50555 i don't think that this is an issue in kamailio source code but i can find where i can configure it

Best approach for Kamailio behind nat
by Evgeny Kuchkov 25 Mar '18

Sorry for my previous mail with typos. I have the current configuration located on google cloud servers: [Alice a.a.a.a]--->(GCN NAT x.x.x.x)--->(Instance with Kam 10.0.0.1)--->(next proxy 10.0.0.2) Currently I have configured a fake alias with IP x.x.x.x in Debain and set listeners this way: listen=udp:10.0.0.1:5060 advertise x.x.x.x:5060 listen=udp:x.x.x.x:5060 200OK from Kam to Alice: Via: a.a.a.a Record-Route: <sip:alias1@10.0.0.2;lr> (used for further internal routing) Record-Route: <sip:alias2@10.0.0.2;lr> Record-Route: <sip:x.x.x.x;lr> Contact: <sip:dnis@x.x.x.x> ACK recived from Alice with reversed RR: ACK sip:dnis@x.x.x.x Via: a.a.a.a Route: <sip:x.x.x.x;lr>, <sip:alias2@10.0.0.2;lr>,<sip:alias1@10.0.0.2;lr> So what Kam does - it goes through loose_route() and dispatches two ACKs to x.x.x.x (from which I'd like to get rid of) and 10.0.0.2 First one is: ACK sip:alias1@10.0.0.2 Via: x.x.x.x Via: a.a.a.a Route: <sip:x.x.x.x;lr>, <sip:alias2@10.0.0.2;lr> And the next one: ACK sip:alias1@10.0.0.2 Via: x.x.x.x Via: x.x.x.x (Doubles Via) Via: a.a.a.a Route: <sip:alias2@10.0.0.2;lr> So my question is - how to make Kam think that x.x.x.x it's own address and stop dispatching in-dialog messages to itself? Currently I'm thinking about chooping off one Route/Record-Route in route[WITHINDLG] tight before loose_route(). But maybe there's a better way to solve my problem?

dlg_manage() and dlg_flag
by Alex Balashov 24 Mar '18

24 Mar '18

Hi, One aspect of the dialog module that is very confusing to newbies is the relationship between the dlg_flag modparam and dlg_manage(). According to the documentation, dlg_manage() effectively seems to obsolete the requirement for a flag[1]: Process current SIP request with dialog module. It is an alternative to setting dialog flag for initial INVITE and Route-parameter-callback execution for within-dialog requests. Yet, if one does not set a dlg_flag modparam, the dialog module fails to load: Mar 23 15:42:29 evaristesys-legacy /usr/local/sbin/kamailio[2900]: ERROR: dialog [dialog.c:500]: mod_init(): invalid dlg flag -1!! Perhaps the flag modparam should be made optional, and any arguments for using one over the other more clearly explained in the documentation. I'd make the latter contribution, but unfortunately am not entirely sure what those are. Cheers, -- Alex [1] https://kamailio.org/docs/modules/5.1.x/modules/dialog.html#dialog.f.dlg_ma… -- 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/

tcpconn_main_timeout
by Kjeld Flarup 23 Mar '18

23 Mar '18

We are developing an app with a pjsip client. I see this error when trying to send an invite from kamailio. Mar 17 00:29:46 raspberrypi /usr/sbin/kamailio[18720]: ERROR: <core> [tcp_main.c:4258]: tcpconn_main_timeout(): connect 62.44.134.85:43829 failed (timeout) A few seconds before 62.44.134.85:43829 did a register. I can understand that either the TCP connection was close by the other end or no one is listening. How much can I see in a pcap from this scenario? I cannot see the invite, but somehow there must be some TCP communication to show what is failing. -- -------------------- Med Liberalistiske Hilsner ---------------------- Civilingeniør, Kjeld Flarup - Mit sind er mere åbent end min tegnebog Sofienlundvej 6B, 7560 Hjerm, Tlf: 40 29 41 49 Den ikke akademiske hjemmeside for liberalismen - www.liberalismen.dk

phonenum module erratic behaviour with 5.1.2
by George Diamantopoulos 22 Mar '18

22 Mar '18

Hello all, It seems that the phonenum module in at least 5.1.2 (haven't tried previous versions) is behaving somewhat erratically. More specifically, if there are any references to any phn PVs with the key other than "number": if ( phonenum_match("1-484-555-8888", "src") ) { xlog("number norm: $phn(src=>number)\n"); xlog("number country: $phn(src=>country)\n"); dbg_pv_dump(30, "L_ERR"); } kamailio will not start: Mar 19 20:06:49 modcom-sbc-dev1 kamailio[5042]: 0(5044) DEBUG: <core> [core/pvapi.c:494]: pv_spec_lookup(): PV <$phn(src=>country)> is not in cache Mar 19 20:06:49 modcom-sbc-dev1 kamailio[5042]: 0(5044) DEBUG: phonenum [phonenum_pv.c:160]: pv_parse_phonenum_name(): phonenum [src] - key [country] Mar 19 20:06:49 modcom-sbc-dev1 kamailio[5042]: 0(5044) ERROR: phonenum [phonenum_pv.c:205]: pv_parse_phonenum_name(): error at PV phonenum name: src=>country Mar 19 20:06:49 modcom-sbc-dev1 kamailio[5042]: 0(5044) ERROR: <core> [core/pvapi.c:951]: pv_parse_spec2(): pvar "phn" has an invalid name param [src=>country] Mar 19 20:06:49 modcom-sbc-dev1 kamailio[5042]: 0(5044) ERROR: <core> [core/pvapi.c:1106]: pv_parse_spec2(): wrong char [)/41] in [$phn(src=>country)] at [17 (5)] Mar 19 20:06:49 modcom-sbc-dev1 kamailio[5042]: 0(5044) ERROR: xlog [xlog.c:513]: xdbg_fixup_helper(): wrong format[number country: $phn(src=>country) If I comment the offending line, all is well, but when dumping PVs with dbg_pv_dump(30, "L_ERR");, only $phn(src=>number) is listed, not the other keys (country, operator, region according to the docs) However, what is more disturbing is that phn(src=>number) always contains the string provided to phonenum_match() function, even if invalid characters are included, with no normalization. For example: phonenum_match("14~8%^88", "src") will result in dbg_pv_dump reporting: "$phn(src=>number)": "14~8%^88" Please note that I'm using sipwise's debian repository for stretch for kamailio, and debian's stable stretch repository for libphonenumnber (currently at 7.1.0-5+b1). I have also tried building current libphonenumber myself (version v8.9.2), but the result is the same. Is this a bug? Or am I missing something? Thanks! BR, George

Kamailio behind NAT no Audio
by Benjamin Marty 22 Mar '18

22 Mar '18

Hi, I am new to Kamailio and coming a bit from the Asterisk side. Currently I'm using the Amazon EC2 Infrastructure and set up an Kamailio with standard configuration. EC2 uses Destination NAT on their side. Thus I enabled WITH_NAT and WITH_NATSIPPING. I'm using the rtpproxy from master branch of https://github.com/miconda/rtpproxy. Besides those two parameters I also changed the listen parameter in the Kamailio config: listen=udp:10.0.0.221:5060 advertise 52.59.XXX.XXX:5060 My rtpproxy is running with following parameters: ./rtpproxy -A 52.59.XXX.XXX -F -l 10.0.0.221 -m 20000 -M 30000 -s udp:*:7722 -d INFO When I use two Softclients (Zoiper) on different Networks (with Source NAT on the Firewall) the Softclient tries to transmit the RTP Packets to the Public IP of the other Network. But the Client obviously thus doesn't get the RTP Packets. Is there an easy and documented way to solve that issue? If I understood it correctly Kamailio together with rtpproxy should be able to receive the RTP Packets and forward them to the other client. So it should signal the IP of the Kamailio to send the RTP packets to. Or am I on the complete wrong way? Regards, Benjamin

drouting & rd
by Jean Cérien 22 Mar '18

22 Mar '18

Hello I have setup 2 gateways in my dr_rules: 5,6 - so the 2nd one is tried if the first fails. The second one requires credentials. When the first one fails: I execute the following code: failure_route[ROUTEFAIL] { if ( t_check_status("[345][0-9][0-9]") or (t_branch_timeout() and !t_branch_replied() )) { t_on_failure("ROUTEFAIL"); if (use_next_gw()) { xlog("L_INFO","failure_route(ROUTEFAIL) @@ routing to: rd: $rd, ru:$ru, t_relay"); t_relay(); exit; } then in the same ROUTEFAIL (before this code), I have if (t_check_status("401|407")) { xlog("L_INFO","failure_route(ROUTEFAIL) @@ call to uac_auth(), $si rd: $rd\n"); ..... So, when the first gateway replies with a 404, it executes correctly the first block, finds the second gw and I see in the log that rd is set to its address. Yet, when the 2nd gw replies with 401, rd is set to the very first gw. However, the pcap traces confirm it is indeed the second that replies this. If this behaviour is correct, I cant seem to find the source IP of the gateway that replied to me, to retrieve credentials from the db. version: kamailio 5.0.5 / 5.0.6 (tested on both) Thank you for your help J

Hi all, I have kamailio setup that uses a mongo cluster, and everything works fine. Only I have problems with the avpops module. The avp_db_load fails with "field [attribute] not found in result iterator", even if the attribute field is present in the object in mongo. Does anybody know what could be going wrong?

How does Kamailio decide which msg to store when receiving it double from 2 servers?
by Zigelman, Amit 21 Mar '18

21 Mar '18

I am using Captagent on 2 sip servers communicating with each other. Both Captagents then route the SIP traffic to the same Kamailio. Therefore, if I understand, Kamailio will get every msg between them twice. Once from server A and once from server B. Let's say that each of them has a different capturing code (100 for server A and 200 for server B) How will the data look in the DB? Will it hold both entries pretty much the same with a difference is some fields such as the capture node? Thanks a lot, Amit -- *Amit Zigelman* | *Software Developer* Mobile (+972) 54-570-9129 <+972%254-570-9129> | amit.zigelman(a)vonage.com

authenticating to mongodb fails
by hdssdsdsdsfsdf hdssdsdsdsfsdf 21 Mar '18

21 Mar '18

When I connect using mongo, the credentials work: $ mongo kamailio -u "kam" -p "kam" MongoDB shell version v3.4.9 connecting to: mongodb://127.0.0.1:27017/kamailio MongoDB server version: 3.4.9 > db.subscriber.find() { "_id" : ObjectI ... But when I use the following DBURL in kamailio.cfg, kamailio fails to even login to mongo: #!define DBURL "mongodb://kam:kam@localhost/kamailio" If I disable mongodb authentication, kamailio starts up just fine again. Any idea what's going wrong here?

NATDETECT Flag 16
by Duarte Rocha 21 Mar '18

21 Mar '18

Greetings, I have a doubt about the flag 16 used in nat_uac_test() belonging to the module NATDETECT. In the documentation, the following is stated : *16* - Test if the source port is different from the port in the “Via” header I have some situations that I receive a request from port 5060 and the Via Header contains no port. I think it probably assumes that it is the default port. Will this situation trigger the "16" flag ? Thanks in advance, Cheers

S-CSCF can not allocate memory
by tyd 21 Mar '18

21 Mar '18

Hello, I haved install debian 8 and kamailio 4.4.7 for IMS testing. After registering 10000 users, SIPp generates CPS 25 SIP INVITE message and BYE message after 100 seconds. After about 240000 calls, there are "cannot allocate memory" messgae on S-CSCF. The command of S-CSCF is "kamailio -m 512 -f /etc/scscf/kamailio.cfg" The parameter mem_join=1 is included in kamailio.cfg. I have modified the share memory to 1024 and 2048, but the result is the same, just increasing the pass calls. Would you please tell me how to solve the memory problem? Thanks.

execute only on INITIAL INVITE
by David Villasmil 20 Mar '18

20 Mar '18

Hello guys, I want to execute an sql only for INITIAL INVITEs, I'm trying like: #!ifdef WITH_DID_VALIDATE if(!has_totag()) { sql_query("acd", "select * from did_numbers where didNumber = '$tU' and active = 'Y'", "ra"); xlog("L_ERR", "[REQUEST_ROUTE] number of rows in table domain: $dbr(ra=>rows)\n"); if( $dbr(ra=>rows)==0 ) { xlog("L_ERR", "[REQUEST_ROUTE] DID Number validation returned [$dbr(ra=>rows)], not responding to this request\n"); exit; } sql_result_free("ra"); } #!endif But, say I remove the DID from the allowed list while a call is going on. Then responses to the allowed INVITE would not be processed. How would I limit that to ONLY the INITIAL INVITE? Should I use has_totag? Thanks!

Security announcement related to Kamailio
by Henning Westerholt 19 Mar '18

19 Mar '18

Hello, as already announced from Daniel-Constantin Mierla on the lists last Wednesday [1], we strongly advise you to update your Kamailio installation to the latest stable release for security reasons. All supported releases (4.4, 5.0. and 5.1) contains two important security fixes related to the tmx and lcr module. Technical details for the tmx issue: A specially crafted REGISTER message with a malformed branch or From tag triggers a so called "off-by-one heap overflow". This vulnerability existed in the tmx module and makes it possible to remotely crash the Kamailio service. If an attacker sends many of this messages this would lead to a Denial of Service of the attacked infrastructure. This is especially critical as no authentication for the remote source is needed. This vulnerability was found from Sandro Gauci and Alfred Farrugia from the Security Company Enable Security. Many thanks to them for finding the issue and reporting it to us. You find all the details including a proof of concept code in the published security announcement from them: https://github.com/EnableSecurity/advisories/tree/master/ES2018-05-kamailio… Technical details for the lcr issue: A vulnerability existed in the lcr next_gw() function. It happens when a very long R-URI username is sent with an INVITE due to an mistake in the function error code handling. It can be triggered from a remote source, but should be only from a trusted peer, as it expected that calls going through lcr are authenticated by user or IP address. This vulnerability was reported from an user in the Netherlands to us, thanks as well for the bug report. So far we are not aware of any public exploits of this errors. But as already mentioned, we advise you to update your Kamailio servers to the latest stable release as soon as possible, especially as the tmx vulnerability will reported to more security lists later today. Please address any detailed technical questions related to the two bugs to the developer list at sr-dev(a)lists.kamailio.org . In case of confidential remarks related to this or other security issues, please address them to the Kamailio Management at management(a)kamailio.org . Best regards, Henning Westerholt Kamailio Project [1] https://lists.kamailio.org/pipermail/sr-users/2018-March/100672.html

msilo on proxy in front of registrar
by Stefan Sayer 19 Mar '18

19 Mar '18

Hello, I have a bit of a strange situation where I want to add SIP MESSAGE reliability (store and forward) for a proxy that is in front of the (message-wise unreliable) registrar/message originator. So I m_store MESSAGEs in the failure_route of MESSAGE requests. By default, msilo's m_dump works only for REQUEST_ROUTE, thus I can't use that in the 200 to REGISTER. But when I add a function to msilo for ONREPLY_ROUTE (without the check for MESSAGE support) it works. So, is there a reason that there's m_dump only for REQUEST_ROUTE? And, is this: if ((msg->first_line).type == SIP_REQUEST) the correct way to check whether we're handling a request or reply? Also, is there a way to check the expires of contacts in the 200 to REGISTER from the script, so I don't try to m_dump on de-REGISTER? Or does this have to go into the m_dump function for the ONREPLY_ROUTE case? Many thanks for hints! Stefan
