kamailio integration with MS teams.
by Yuriy Nasida 14 Apr '20

14 Apr '20

Do you have some expirience with kamailio integration with MS teams ? I follow the instructon from here https://skalatan.de/en/blog/kamailio-sbc-teams TLS part is configured correctly. I also got OPTIONS pings working between MS teams and kamailio by following of this instruction. That is very good. But... There is issues with outbound calls from MS teams to kamailo. MS side send INVITE, kamailio responds with 180 and 200 OK, but looks like MS ignores us. I know that I probably should use record_route_preset function here to modify Record-Route headers to satisfy MS wishes. But nothing helps. I also tried to modify contact header in 200 OK like it was done for OPTIONS - no luck. Anyone has a working example of kamailio files for MS team ? Or at least sucessful pcap with them. I can be wrong but looks like MS doesn't respect RFC at all. Thanks.

H264 codec licence
by Prakash Ganesan 14 Apr '20

14 Apr '20

Hi, We are planning to use kamilio/RTP engine for our WebRTC calls. I would like to know how the H264 codec licences are handled as i know there is a royalty fee associated with this video codec from the server perspective. As of now there is plan to use H264 pass through and vp8/vp9 transcoded to H264 by the kamilio/RTP engine. -- Cheers Prakash

Using dispatcher module : Modifying message before dispatching with send_udp()
by Luis Rojas G. 13 Apr '20

13 Apr '20

Hello, I am using the dispatcher module, Kamailio version 5.3.3. The point is, I am using send_udp() to forward the message, because I don't want Kamailio to add headers Via nor Record-Route. I am just dispatching the Invite message, and the rest of communication to be made just between the endpoints, not through Kamailio. However, I need to add before a custom header, using append_hf(). It seems, send_udp() really changes nothing at all in the message, not even something added by the script with append_hf(). It works if I use forward(), but not if I use send_udp(). Is there a way to accomplish this? Best regards, -- Luis Rojas Software Architect Sixbell Los Leones 1200 Providencia Santiago, Chile Phone: (+56-2) 22001288 mailto:luis.rojas@sixbell.com http://www.sixbell.com

Greetings, How much time will Kamailio keep a transaction active if the ACK to a INVITE is never received by Kamailio? Best Regards,

Using Stir/Shaken with Kamailio
by Alexandru Tripon 13 Apr '20

13 Apr '20

Hi, After I watched the talk about Stir/Shaken(https://vimeo.com/396940577), I wanted to try the module(secsipid), but I couldn't make it work. I built the Kamailio from source using the following steps: https://kamailio.org/docs/tutorials/devel/kamailio-install-guide-git/ . And then built the secsipid following the instruction found here: https://www.kamailio.org/docs/modules/devel/modules/secsipid.html#idm90 . But when I start the Kamailio with the module loaded I get the following error: ` kamailio: ERROR: <core> [core/sr_module.c:325]: version_control(): no version info in module </usr/local/lib64/kamailio/modules/secsipid.so>: /usr/local/lib64/kamailio/modules/secsipid.so: undefined symbol: module_version ` How can I fix this? Thank you in advance, Alexandru Tripon

Callee BYE routing issue
by Daniel W. Graham 13 Apr '20

13 Apr '20

Have an issue with BYE routing in a lab setup, any suggestions on what I should be looking at? Topology: UA1 <-> NAT device 1 <-> Proxy1 <-> Registrar/B2BUA <-> Proxy1 <-> NAT device 1 <-> UA2 All UA to UA calls flow through B2BUA. All IP’s are public except for UA1 and UA2. -Both endpoints can call each other. -If the caller hangs up first, BYE is routed properly. -If the callee hangs up first, BYE causes proxy to send 478. On calls where BYE results in 478: if(!isdsturiset()) { ……….…………………….not executed handle_ruri_alias() } return; Example issue call: UA2 to UA1, UA1 hang-up.

Hi David, Kindly help me in this regard. I am not getting like it is because of pval issue or some other issue which causes this issue. I have configured kamailio as an IMS server as VM based .

The *registration is happening properly* in my both zoiper clients for hss configured users (alice and bob). When i am making an *INVITE , *I am getting *403 Forbidden - Domain not served *error from SCSCF. The Call Flow for invite is as follows . call from alice(a)sip.example.com zoiper1 (UE) -> PCSCF ( INVITE sip:bob@sip.example.com;transport=UDP ) PCSCF -> SCSCF ( INVITE sip:bob@sip.example.com;transport=UDP ) SCSCF -> PCSCF (100 trying) SCSCF -> ICSCF ( INVITE sip:bob@sip.example.com;transport=UDP ) ICSCF -> SCSCF (100 trying) ICSCF -> SCSCF ( INVITE sip:bob@sip.example.com;transport=UDP ) SCSCF -> ICSCF (100 trying) SCSCF -> ICSCF (*403 Forbidden - Domain not served*) ICSCF -> SCSCF (Request: ACK sip:bob@sip.example.com | ) ICSCF -> SCSCF ( 403 Forbidden - Domain not served ) SCSCF -> PCSCF ( 403 Forbidden - Domain not served ) PCSCF -> UE ( 403 Forbidden - Domain not served ) Below are the alias configuration i have done in pcscf,icscf,scscf nodes *PCSCF.CFG* # IP-Adress for incoming SIP-Traffic, in the following format: # SIP / UDP listen=udp:10.x.x.179:4060 # SIP / TCP listen=tcp:10.x.x.179:4060 # SIP / TCP/TLS listen=tls:10.x.x.179:4060 # IPSEC / UDP #!define IPSEC_LISTEN_ADDR "0.0.0.0" #!define IPSEC_CLIENT_PORT 5062 #!define IPSEC_SERVER_PORT 5063 #alias="sip.example.com:4060" alias=pcscf.sip.example.com:4060 #!define MY_WS_PORT 80 #!define MY_WSS_PORT 443 #!define PCSCF_URL "sip:pcscf.sip.example.com:4060" #!define TCP_PROCESSES 8 #!subst "/NETWORKNAME/sip.example.com/" #!subst "/HOSTNAME/pcscf.sip.example.com/" *ICSCF.CFG* # SIP / UDP listen=udp:10.x.x.79:4070 # SIP / TCP listen=tcp:10.x.x.79:4070 # SIP / TCP/TLS listen=tls:10.x.x.79:4071 alias="icscf.sip.example.com:4070" #!define NETWORKNAME "sip.example.com" #!define HOSTNAME "icscf.sip.example.com" *SCSCF.CFG* # SIP / UDP listen=udp:10.x.x.73:4080 # SIP / TCP listen=tcp:10.x.x.73:4080 # SIP / TCP/TLS listen=tls:10.x.x.73:4081 #!define NETWORKNAME "sip.example.com" #!define HOSTNAME "scscf.sip.example.com" #!define URI "sip:scscf.sip.example.com:4080" alias=scscf.sip.example.com:4080 # ENUM-Server to query: #!define ENUM_SUFFIX "scscf.sip.example.com."
