How to overwrite DisplayName
by Stefano Larosa 05 Jun '20

05 Jun '20

Hi and first of all thanks for your amazing work. I have a kamailio 5.1.1 and i need to change the DisplayName before sending INVITE to another Asterisk server. I need that "Sergio"<+33558700000(a)80.169.227.18> Becomes "Simona"<+33558700000(a)80.169.227.18> I've tried just changing $fn value: $fn="Simona" Or using uac_replace_from("Simona ",""); But INVITE msg is always From: "Sergio"<sip:+33558700000@80.169.227.18;transport=UDP>;tag=1ac9e066 I've tried this options in different position in kamailio.cfg but i can figure out the problem. Do you have any suggest? Thank you, Stefano.

Kamailio under NAT
by Aidar Kamalov 05 Jun '20

05 Jun '20

Hello, I am trying to start kamailio+rtpengine+asterisk in docker with docker-compose (not in network host mode). And I faced behavior that I can't understand. When my phone(fanvil) sends a register to kamailio with his ip in contact - 192.168.88.55 (to host's ip address 192.168.88.55), kamailio 200OK answers with "received=172.18.0.1" param in Via. (172.18.0.1 it is host's docker interface, kamailio's ip is 172.18.0.4) After that my phone unregisters with Expires: 0 and sends a new register with 172.18.0.1 in contact. Is that correct? Is there any way to fix this? 2020/06/05 12:05:51.764617 172.18.0.1:46142 -> 172.18.0.4:5060 REGISTER sip:192.168.88.55 SIP/2.0 Via: SIP/2.0/UDP 192.168.88.100:5756;branch=z9hG4bK14305253915361123;rport From: akamvm <sip:1000@192.168.88.55:5060>;tag=1125027099 To: akamvm <sip:1000@192.168.88.55:5060> Call-ID: 2849918516212-27188555511609(a)192.168.88.100 CSeq: 1 REGISTER Contact: <sip:1000@192.168.88.100:5756> Max-Forwards: 70 Expires: 3600 Supported: path User-Agent: Fanvil X3S 2.10.2.6887 0c383e217eb9 Allow: INVITE, ACK, OPTIONS, BYE, CANCEL, REFER, NOTIFY, INFO, PRACK, UPDATE, MESSAGE Content-Length: 0 2020/06/05 12:05:51.765716 172.18.0.4:5060 -> 172.18.0.1:46142 SIP/2.0 200 OK Via: SIP/2.0/UDP 192.168.88.100:5756 ;branch=z9hG4bK14305253915361123;rport=46142;received=172.18.0.1 From: akamvm <sip:1000@192.168.88.55:5060>;tag=1125027099 To: akamvm <sip:1000@192.168.88.55:5060 >;tag=1cbccc00ba5f7d13255bc12726ccacc5.59da Call-ID: 2849918516212-27188555511609(a)192.168.88.100 CSeq: 1 REGISTER Contact: <sip:1000@192.168.88.100:5756>;expires=3600 Server: kamailio (5.2.1 (x86_64/linux)) Content-Length: 0 2020/06/05 12:05:51.779447 172.18.0.1:46142 -> 172.18.0.4:5060 REGISTER sip:192.168.88.55 SIP/2.0 Via: SIP/2.0/UDP 192.168.88.100:5756;branch=z9hG4bK251317807114669601;rport From: akamvm <sip:1000@192.168.88.55:5060>;tag=1125027099 To: akamvm <sip:1000@192.168.88.55:5060> Call-ID: 2849918516212-27188555511609(a)192.168.88.100 CSeq: 2 REGISTER Contact: <sip:1000@192.168.88.100:5756> Max-Forwards: 70 Expires: 0 Supported: path User-Agent: Fanvil X3S 2.10.2.6887 0c383e217eb9 Allow: INVITE, ACK, OPTIONS, BYE, CANCEL, REFER, NOTIFY, INFO, PRACK, UPDATE, MESSAGE Content-Length: 0 2020/06/05 12:05:51.780479 172.18.0.4:5060 -> 172.18.0.1:46142 SIP/2.0 200 OK Via: SIP/2.0/UDP 192.168.88.100:5756 ;branch=z9hG4bK251317807114669601;rport=46142;received=172.18.0.1 From: akamvm <sip:1000@192.168.88.55:5060>;tag=1125027099 To: akamvm <sip:1000@192.168.88.55:5060 >;tag=1cbccc00ba5f7d13255bc12726ccacc5.f669 Call-ID: 2849918516212-27188555511609(a)192.168.88.100 CSeq: 2 REGISTER Server: kamailio (5.2.1 (x86_64/linux)) Content-Length: 0 And new register: 2020/06/05 12:05:51.780287 172.18.0.1:46142 -> 172.18.0.4:5060 REGISTER sip:192.168.88.55 SIP/2.0 Via: SIP/2.0/UDP 192.168.88.100:5756;branch=z9hG4bK2696168232620424454;rport From: akamvm <sip:1000@192.168.88.55:5060>;tag=2649930762 To: akamvm <sip:1000@192.168.88.55:5060> Call-ID: 257831362525663-2610472014851(a)172.18.0.1 CSeq: 1 REGISTER Contact: <sip:1000@172.18.0.1:46142> Max-Forwards: 70 Expires: 3600 Supported: path User-Agent: Fanvil X3S 2.10.2.6887 0c383e217eb9 Allow: INVITE, ACK, OPTIONS, BYE, CANCEL, REFER, NOTIFY, INFO, PRACK, UPDATE, MESSAGE Content-Length: 0 2020/06/05 12:05:51.781208 172.18.0.4:5060 -> 172.18.0.1:46142 SIP/2.0 200 OK Via: SIP/2.0/UDP 192.168.88.100:5756 ;branch=z9hG4bK2696168232620424454;rport=46142;received=172.18.0.1 From: akamvm <sip:1000@192.168.88.55:5060>;tag=2649930762 To: akamvm <sip:1000@192.168.88.55:5060 >;tag=1cbccc00ba5f7d13255bc12726ccacc5.4b3b Call-ID: 257831362525663-2610472014851(a)172.18.0.1 CSeq: 1 REGISTER Contact: <sip:1000@172.18.0.1:46142>;expires=3600 Server: kamailio (5.2.1 (x86_64/linux)) Content-Length: 0 -- Aydar A.

Kamailio 5.3.0 and HEPv3 oversized traffic
by Karsten Horsmann 04 Jun '20

04 Jun '20

Hi list, I saw some strange behavior in Kamailio 5.3.0 with HEPv3. My Kamailio serves webrtc and sip tls and captures that to an Homer 7.7 instance. I see only the UAC Parts of the message and not the answers from Kamailio in that scenario. Maybe I reached the max Paket size for udp. Hard to debug. In production I saw everything (but there I used and older Kamailio 5.2.x and Homer 5.5 which can handle fragment udp). Any ideas how to hunt the root cause of the problem? Cheers Karsten

kamcmd mtree.match
by Volker Denneberg 03 Jun '20

03 Jun '20

Hi, given this mtree kamcmd mtree.list siteId { tname: siteId tprefix: 00492419697994 tvalue: { 00492419697994 2388 } } { tname: siteId tprefix: 492415310752 tvalue: { 492415310752 2388 } } i wonder why this lookup fails: kamcmd mtree.match siteId 49241531075212 0 error: 500 - Invalid Parameters My expectation was that 2nd tprefix should match. I am using modparam("mtree", "db_table", "mtrees") modparam("mtree", "char_list", "0123456789+") modparam("mtree", "mt_tree_type", 0) # payload type for tree data : string Thanks in advance, Volker

Trouble loading multiple javascripts with KEMI
by Benjamín Visón 03 Jun '20

03 Jun '20

I am using the module *app_jsdt *with *KEMI *and I am having trouble loading multiple javascript files. The interpreter only notices the last file that's loaded. What I am trying to do is separate my logic so that everything is not inside the kamailio.conf.js (or the main file the contains the necessary functions if you will). modparam("app_jsdt", "load", "/etc/kamailio/file1.js") modparam("app_jsdt", "load", "/etc/kamailio/file2.js") cfgengine "jsdt" In the example above, only functions in file2 are recognized. I am aware that I can use jsdt_run or jsdt_load but from KEMI I don't see a clear way to link this with things like events and timers or replies that don't necessarily go through the *request_route*. (As a plus, I am wondering on performance on Javascript vs Python/Lua and if it's viable on high load, if anyone can throw 2 cents on that it would be helpful!)

Polycom looses registration within cluster scenario.
by Zhan Bazarov 03 Jun '20

03 Jun '20

Hello. We faced to an issue with polycom, namely - polycom phones looses registration within SRV/DNS based cluster scenario.. So we have round-robin cluster of SIP-proxy instances behind the same SRV/A records(each instance has the same weight). The initial registration works fine, but after the polycom sends a SUBSCRIBE request to another one sipProxy instance(because of round-robin scenario) - polycom stops sending re-register by expires which we are providing in 200Ok message... So the idea is to keep polycom located on the instance where initial register request came to. But polycom is sending SUBSCRIBE in shuffle(not to the server where registration is located) We can solve this issue by keeping registration on lines not on main SIP configuration itself, otherwise polycom looses registration from cluster at all. But it lead to rejecting some calls by polycom with '400 bad request.. We can solve it by disabling validation. But it leads to additional things like: polycom has multiple registrations on the device itself.. I mean, for example, first one registration isn’t expired, and polycom has two registrations at the same time... any ideas? How we can avoid this issue right? Thanks. -- Sent from: http://sip-router.1086192.n5.nabble.com/Users-f3.html

Received ipv6 problem
by Ahmed Marsou 03 Jun '20

03 Jun '20

Hi; I'm using the received parameter to send a MESSAGE to unregsiter the first user that is registered to register the second one. Using: *modparam("usrloc", "received_column"* *modparam("registrar|nathelper", "received_avp",* and when I do a: select received from location; as you can see is null. +----------+ | received | +----------+ | NULL | +----------+ In IPV4 is working fine, but in IPV6 is not. Can you tell me how can I get this value? Im going crazy with that. reg_fetch_contacts("location", "$fu", "existingContact"); if( $(ulc(existingContact=>user_agent)[0]) =~ "SPI/v"){ $var(oldDeviceId) = $(ulc(existingContact=>callid)[0]{s.substr,9,0}); $var(newDeviceId) = $(hdr(Call-ID){s.substr,9,0}); if($var(oldDeviceId) != $var(newDeviceId) ){ xlog("L_INFO","New device id is different:warn previous user another user overide him"); $var(address) = $(ulc(existingContact=> *received*)[0]); $var(ruri) = $(var(address){s.substr,4,0}); #Send a SIP Request signalling the problem and its reason on the body $uac_req(method)="MESSAGE"; $uac_req(ruri) = "sip:"+ $au + "@" + $var(ruri); $uac_req(furi) = "sip:kamailio@sip_domain"; $uac_req(turi) = $fu; $uac_req(hdrs)="Max-Forwards: 70\r\nEvent: reg\r\nContent-Type: text/plain\r\nAccept-Contact:*;+g.ext.app.registration\r\n"; $uac_req(body)="Already registered with another device id"; uac_req_send(); drop; } } Thank you.
