Return value from lua/python/js/bash/etc... function
by Dmytro M 10 Feb '23

10 Feb '23

What is the simplest way to return values from external application into Kamailio config and assign it to a variable? I'm looking for the most light weight mechanism to do it and to offload some logic to external app. Something like this would be ideal: $var(myVar), $var(err) = lua_run("lua_func1", "$rU"); OR $var(encString) = exec_cmd("echo 'abc $rU' | base64"); There is this method: http_client_query("http://...", "", "", "$var(result)"); but there is an overhead of networking and HTTP protocol. Please advise. Thanks, Dmytro

ACK on Reverse Invite is send to NATed Internal port instead of public port
by Angelo Sipper 09 Feb '23

09 Feb '23

Hi, I am having an issue on some outbound calls from nated UAC. On these calls our SBC receive reverse invites from the carrier side within the call. When this happens, my SBC(Kamailio1) sends the invite to UAC and the UAC sends 200 OK (SDP). Unfortunately my SBC(Kamailio1) sends back the ACK not to the correct UAC public port but instead to UAC internal port making the call to crash! My setup has: (TLS)UAC -> (UDP)Kamailio1(UDP) -> (UDP)Kamailio2(TLS) -> Carrier(UDP) Bellow you can find the trace and you can see the ACK send to wrong port on 2023/01/26 09:48:31.254591 Your help will be much appreciated! 2023/01/26 09:48:23.225326 77.1.1.1:2314 -> 17.17.17.211:5060 INVITE sip:300987654321@17.17.17.211:5060 SIP/2.0 Via: SIP/2.0/UDP 192.168.80.228:5060 ;branch=z9hG4bK-524287-1---9bbfa2727a1f3803;rport Max-Forwards: 70 Contact: <sip:301234567890@77.1.1.1:20125> To: <sip:300987654321@17.17.17.211:5060> From: "My, User"<sip:MyTrunk@77.1.1.1:20125>;tag=07ece97c Call-ID: 1q5nE37RGZ8a8ChI6rqShw..

DB_CLUSTER failure with carrierroute (and others?)
by Kaufman 08 Feb '23

08 Feb '23

All, I've been trying to chase down an issue with db_cluster and permissions in combination with something else, where with my full configuration using the same cluster in multiple modules has failures. I've been trying to create a simplified configuration to consistently reproduce the problem without much success, however I did stumble upon THIS particular problem. The configuration here works fine as is - avpops uses the cluster URL, and carrierroute uses the direct SQLite URL. If I define WITH_DBCLUSTER, then carrierroute fails fetching rows using the cluster connection. Note that AVPOPS is only used as a general test to see if the cluster config works. If I remove references to avpops , carrierroute still fails loading from the cluster URL.

Drops on async_route with delay
by Alex Balashov 07 Feb '23

07 Feb '23

Hi, Some percentage of requests processed with async_route("REQ_PROCESS", "5") seem to end up with a resumed transaction, though most do. Not sure what the exact percentage is. The ones that don't Is this due to excessive requests? Is there a limit on internal IPC queue depth? Is it conceptually similar to a generic shared blocking queue internally, along the lines of 'mqueue'? Is there any reasonable way to troubleshoot this? Thanks! -- Alex -- Alex Balashov Principal Consultant Evariste Systems LLC Web: https://evaristesys.com Tel: +1-706-510-6800

Hi, Can DISPATCHER be used in conjunction with ENUM? E.g., to avoid sending requests to SIP destinations that are returned by ENUM, but, which DISPATCHER knows are down? Thanks, Jawaid

nating private uas to public ip addr
by Jack Murphy 06 Feb '23

06 Feb '23

I have a multi-homed kam with a uas behind one private interface and a public interface for the uac+sip provider. When the uac initiates a call, kam sends the invite to the private uas which sets up a b-leg call back to kam with a Contact header that has the uas' private ip address. I want to change that private ip address to be Kamailio's advertised/public ip address before it gets forwarded to the sip provider. I am rewriting Contact in a route from request_route like this: > if ($rP != $null) { > $var(ct) = ";transport=" + $rP; > }else{ > $var(ct) = ""; > } > $var(cr) = "<sip:" + $fU + "@" + $RAi + ":" + $RAp + $var(ct) + ">"; > > remove_hf("Contact"); > append_hf("Contact: $var(cr)\r\n"); This seems to work fine for the INVITE going to the provider. There's also the 200 OK that the uas sends for the uac (a-leg) with a private ip address in Contact -- I want to rewrite that before sending it to the UAC, too. Using the same method as above (but inside onreply_route), what happens is the UAC receives the modified OK and sends back an ACK with the modified Contact (kam's public ip addr) in the ACK r-uri, and kam gets in a loop of sending an ACK from its private ip address to its public ip address and replying to itself. call flows: https://imgur.com/a/Yj2DJpn Is there a right way to do this?

htable: autoexpire vs updatedelete
by Дилян Палаузов 06 Feb '23

06 Feb '23

Hello, https://www.kamailio.org/docs/modules/devel/modules/htable#htable.p.htable says for modparam('htable', 'htable', '…autoexpire … updateexpire…') autoexpire -time in seconds to delete an item from a hash table if no update was done to it. If is missing or set to 0, the items won't expire. updateexpire - if set to 1 (default), the time until expiration of an item is reset when that item is updated. Certain uses of htable may dictate that updates should not reset the expiration timeout, however, in which case this attribute can be set to 0. My reading is that, when a value is updated and autoexpire is positive, autoexpire will reset the timer, but updateexpire may or may not reset the same timer. That is: modparam('htable', 'htable', 'a=>autoexpire=5;updatedelete=1') modparam('htable', 'htable', 'b=>autoexpire=5;updatedelete=0') If b was not updated for 5s, will it be removed, as the documentation for autoxpire suggests, irrespective of updatedelete? Greetings Dilyan

no autocomplete for kamcmd for latest debian packages
by Ovidiu Sas 04 Feb '23

04 Feb '23

Hello, The latest debian packages are built without autocomplete for kamcmd. Do we have the libreadline-dev package installed on the build machine? I know that we have kamctl rpc and kamcli, but if we are still shipping kamcmd, it should have the autocomplete feature enabled.

I try to workout if - currently it would work, or - where and how to debug more: I face - 2 interfacec - public internet (so, TLS + sRTP) is desired and private - old infrastructure - i mus only use plain RTP 172.23.9.70 - private ip - from this endpoint of kamailio and rtpengine should send only basic RTP 172.23.210.75:5060 private - target for kamailio 1.2.3.24 obfuscated public IP (TLS + sRTP required) kamailio 5.4.4 (x86_64/linux) rtpengine -v Version: 11.1.1.4-1~bpo11+1 all i do is: if (proto==TLS) { rtpengine_manage("RTP/AVP ICE=remove replace-session-connection replace-origin pad-crypto ptime=20 codec-transcode-PCMA record-call=on allow-transcoding direction=external direction=internal record-call=on"); } else if ($ru =~ "transport=tls") { rtpengine_manage("DTLS=on SRTP AVPF ICE=remove replace-session-connection replace-origin pad-crypto ptime=20 codec-transcode-PCMA record-call=on allow-transcoding direction=internal direction=external record-call=on media-address=1.2.3.24"); } # 1.2.3.24 obfuscated public IP 172.23.210.75:5060 is in dispatch.cfg, as '11' route[SBC_CORE] { append_hf("X-My-SRTP: removed31337\r\n"); ### i see this text in invtes from kamailio 172.23.9.70 towards 172.23.210.75:5060 ### i see only RTP, so as expected if (!ds_select_dst("11", "0")) { xwarn("I:$var(i) DROP(DOWN!)

transport=ws causing kamailio to use wrong listen socket
by nathan.bruning＠talksome.com 31 Jan '23

31 Jan '23

Hi all, We're hitting an issue while integrating secure websockets in our existing SIP infrastructure using Kamailio. When the registration comes in, it causes an entry in our AOR table, with ";transport=ws" appended. When we want to send a message to this client (using t_relay), kamailio seems to take 'ws' as being *unsecure* websockets. In turn, this makes Kamailio try to send out the message using a TCP listener - while it should have picked the TLS listener. There are some remarks in the sources about ws vs. wss, so i'm struggling to figure out where things go wrong. I've also created github issue #3340 with more details. Any help would be appreciated. If this turns out to be a Kamailio bug, i'm happy to provide a patch.

How can I setup Kamailio for failover on LCR ?
by scramatte 31 Jan '23

31 Jan '23

Hello, How can I setup Kamailio for failover on LCR ? Currently my Kamailio 4.x works with lcr but doesn’t care about gateway status. I mean that if a gateway match rule , it sends the call through without check if the gateway is available an never try the next one if the first fail. I’ve tried to implement inactivate_gw() But I received error that lcr_id_avp is not defined. I’ve added the parameters to lcr module for Ping and enable defunc but I’m unable to get it working. By the way I ‘ve trad that defunct is not a good practice as hacker sending malformed sip header can throw down the gateway. So what is the good and working way to setup outbound call failover ? Regards Sebastien

Evapi Dispatcher 100% cpu.
by Sebastian Sastre 30 Jan '23

30 Jan '23

Hello We are currently using EVAPI to push messages into kamailio from a go app. For the most part ift works without problems, messages get delivered into the event route and we use it to update presence status. Recently we started noticing delays on the evapi processing. After 500 requests x min the pid corresponding to the EVAPI dispatcher gets pegged at 100% CPU and processing of requests starts slowing down until in some cases the connection just drops and we have to reconnect. After that pid drops, the dispatcher goes back to working. Unfortunately the error we get back is very generic and is not telling us much logger.go:39: ERR Handler returned error (write tcp 127.0.0.1:48448->127.0.0.1:8228: write: broken pipe) This only happens on prod servers and with high load which makes it hard to debug. There is no other slowness or increase of traffic or drop SIP traffic, only evapi dispatcher at 100% and the EVAPI workers on idle. Curious if anyone has run into this issue. We've tried different versions (5.4 , 5.5 and 5.6) and it happens on all of them. Any feedback appreciated ! Thanks !

Is preloading openssl_mutex_shared necessary for Kamailio 5.6 or is it not necessary?
by Дилян Палаузов 30 Jan '23

30 Jan '23

Hello, https://www.kamailio.org/docs/modules/devel/modules/tls says: For OpenSSL (libssl) v1.1.x, it is required to preload 'openssl_mutex_shared' library shipped by Kamailio. For more details see 'src/modules/tls/utils/openssl_mutex_shared/README.md'. 'src/modules/tls/utils/openssl_mutex_shared/README.md says: **IMPORTANT: the workaround of using this preloaded shared library is no longer needed starting with Kamailio v5.3.0-pre1 (git master branch after September 14, 2019). The code of this shared library has been included in the core of Kamailio and the same behaviour is now achieved by default.** This is a shared library required as a short term workaround for using Kamailio with OpenSSL (libssl) v1.1. It has to be pre-loaded before starting Kamailio. In v1.1, libssl does not allow setting custom locking functions, using internally pthread mutexes and rwlocks, but they are not initialized with process shared option (PTHREAD_PROCESS_SHARED), which can result in blocking Kamailio worker processes. Is preloading openssl_mutex_shared necessary for Kamailio 5.6 or is it not necessary? If it is not necessary, why isn’t it removed from the source code? Greetings Дилян

Locally generated BYE sent to private IP
by James Lipski 27 Jan '23

27 Jan '23

Hi all, I'm doing some experimenting with kamailio -- currently looking for a replacement of our existing (aging) SIP infrastructure. One of the experiments that I'm doing is testing the dialog module's dlg_set_timeout function. The issue that I'm having is while I do see that kamailio is generating a BYE, and sends it out to the B-leg of the call properly, the BYE goes to a private address on the A-leg. To Note: - kamailio is behind a NAT (on AWS) - both UA endpoints are remote and are both behind a NAT - Not sure if this matters, but I do have the topos module enabled, though I see the same behavior regardless if it's enabled or not. - Have set nathelpers (fix_nated_register, fix_nated_contact,etc...) which helps calls between endpoints and the endpoints themselves are able to send/receive BYEs when they generate them; however doesn't seem to help if kamailio locally generates the BYE. The only thing I do see within my logs is when the BYE is being generated by kamailio, it uses the private IP of my UA and not public for the caller. Callee, the public address is referenced. If more information is needed, please let me know (just didn't want to spam my script/ logs). Thanks.

topos vs topoh, any reason for putting a private IP in the Contact header?
by Benoit Panizzon 27 Jan '23

27 Jan '23

Hi I'm trying to work around Route-Header and Via Issues with the two topology hiding modules topoh and topos and trying to figure out, which one works better for our environment. My conclusion so far: topos creates very clean header, but needs a database or redis. I'm always reluctant in adding more components which could fail or cause load. topoh also works, but it worries me a bit that according to the manual: https://www.kamailio.org/docs/modules/devel/modules/topoh.html#topoh.p.mask… a private IP is used to mask the contact header. I have come across a CPE which, as far as I see, is misbehaving by ALWAYS sending a PRACK to the Hostname or IP found in the Contact header, and ignoring Route and Via Header. So why using a private IP as 'mask' and not the IP or Hostname of the actual kamailio instance?

RTPengine multiple setID sockets
by John Hardiman 24 Jan '23

24 Jan '23

Hi All, Hope you are all well? I am hoping you can help with a bit of syntax I am struggling to get working in the intended way. (We are using Kamailio 5.5.3 and using Kemi/python.) The scenario is in AWS where we have separate Kamailio and RTPengine instances, with a cluster of FreeSWITCH EC2's on private addresses only. In the current setup, all RTP routes via the NAT gateway and back to the private IP of the selected FreeSWITCH (and vice versa). This works in the current config, but I would want this traffic not going via the NAT gateway and use the private address and route internally on the VPC. (These EC'2 have only 1 network interface and that cannot be changed for this work.) So anything between FreeSWITCH and Kamailio/RTPengine uses the private IP's for media, the rest use public IP's. It is good to note that the RTPengine's are the same in each set (3 total RTPengine's), just using the public/private IP's based on set ID. My first aim is to use KSR.permissions.allow_source_address() to check if the source address is from the FreeSWITCH cluster and set the rtpengine setID based on this. I have used this method for different parts of the config and it works. I am failing at this first step it seems, as no matter what I use in the function (below) it defaults and uses the public IP's in SDP. (No matter if I use the same setID in each set) kamailio.cfg snippet: # ----- rtpengine params ----- modparam("rtpengine", "setid_avp", "$avp()") # Public IP's ID 1: modparam("rtpengine", "rtpengine_sock", "1 == udp:5.5.5.5:2223 udp:6.6.6.6:2223 udp:7.7.7.7:2223") # Internal IP's ID 2: modparam("rtpengine", "rtpengine_sock", "2 == udp:10.0.0.1:2223 udp:10.0.0.2:2223 udp:10.0.0.3:2223") Kemi file snippet: # RTPengine Options for different SetID def ksr_route_rtpengine(self, msg): if KSR.textops.has_body_type("application/sdp") > 0 : # Source address is private subnet - use RTPengine set 2 (private IP's) if KSR.permissions.allow_source_address(400) == 1: KSR.rtpengine.set_rtpengine_set(2) KSR.rtpengine.rtpengine_manage( "RTP/AVP replace-session-connection replace-origin port-latching ICE=remove") else: # Source address is NOT private - use RTPengine set 1 (public) KSR.rtpengine.set_rtpengine_set(1) KSR.rtpengine.rtpengine_manage( "RTP/AVP replace-session-connection replace-origin port-latching ICE=remove") KSR.xlog.xlog("L_INFO", "RTPengine handling Block") return 1 Group 400 is the private subnet of the FreeSWITCH clusters we have behind on private addresses and the list contains the subnet of private IP's. Using the above, the Kamailio starts fine and understands/loads each set of RTPengine's and calls work with audio. but regardless of the set number used (even only using set 2 in both) it defaults to public IP's in the SDP. (This is the only place in the config where this function is defined) My SDP from FreeSWITCH egress to Kamailio/RTPengine has private IP's in the SDP. The only thing I do not fully understand is the setid_avp - specifically $avp() block and if this needs to stay empty, or be duplicated with the set ID in each one. Any help would be greatly appreciated in understanding where I am going wrong here. Thanks, John.

dialog: db_mode => 1, enable_dmq => 1 but entries not replicated to 2nd node DB
by Benoit Panizzon 24 Jan '23

24 Jan '23

Hi I am struggling with DMQ and dialog DB storage leading to orphan or duplicate entries in database and not loading all dialog information upon restart. usrloc on the other side, also using local db storage and dmq, works flawlessly even when restarting one node. All location information is replicated between the databases via DMQ. So trying to find what is different. usrloc module: modparam("usrloc", "db_url", DBLOCAL) modparam("usrloc", "db_mode", 2) modparam("dmq_usrloc", "enable", 1) modparam("dmq_usrloc", "sync", 1) dialog module: modparam("dialog", "db_url", DBLOCAL ) modparam("dialog", "db_mode", 1 ) modparam("dialog", "db_skip_load", 0) modparam("dialog", "enable_dmq", 1) via kamcmd dlg.list I see that dialog information is being replicated between the two nodes. But I can only find the dialog in the local database of the node which is handling the call. Is this the expected behavior? I also just found how to create duplicate entries in the database... * Run a call on Node A, verify the dialog information is store in the local database and replicated to node B via DMQ. * Restart Kamailio on Node A. There I suspect, node A is restoring Dialog Information via DMQ from Node B and loading the same information from database, leaving duplicates in dialog_vars.
