Can following scenario be implemented using Kamilio
by Jayanth Acharya 03 Mar '15

03 Mar '15

Would like to know if Kamilio (in it's sip-proxy role) could be configured to somehow take note of the 'Contact:' header of a 302 response from B-party, to forward the INVITE to C-party (specified by the updated Contact URI) ? Alternatively, is there a way for the B-party SIP UAS to get the proxy (Kamilio) to forward the INVITE (from A-party) to C-party ? Does Kamilio have to be configured to act in a specific / non-default role ? In doing so, B-party receives no further SIP messages for this particular dialog. thanks, J

Hello Daniel, Is notify should follow subscribe routes ? Here SUBSCRIBE completely look normal to me. <--- SIP read from UDP:10.18.130.46:5060 ---> SUBSCRIBE sip:10102@networklab.ca SIP/2.0 Record-Route: <sip:kamailio_pub_ip:5081;transport=tls;lr=on;ftag=08c99307d3;nat=yes> Accept: application/simple-message-summary Via: SIP/2.0/UDP 10.18.130.46;branch=z9hG4bKdee2.b83c2028dc57c641d2b8cad968347d6a.0;i=2 Via: SIP/2.0/TLS 192.168.0.16:5063;rport=5063;received=client_pub_ip;branch=z9hG4bK0c54032bd8905d262 Max-Forwards: 69 From: "10102" <sips:10102@networklab.ca>;tag=08c99307d3 To: <sips:10102@networklab.ca> Call-ID: cea703eb8c21f709 CSeq: 1096440084 SUBSCRIBE Allow: ACK, BYE, CANCEL, INVITE, MESSAGE, NOTIFY, OPTIONS, REFER, SUBSCRIBE, UPDATE Allow-Events: message-summary Authorization: Digest username="10102",realm="networklab.ca",nonce="29ac01f1",uri="sips:10102@networklab.ca",response="0298c2a93bdd4969a3cd0b757d671dbb",algorithm=MD5 Contact: <sips:10102@client_pub_ip:5063>;audio Event: message-summary Expires: 3600 Supported: eventlist, replaces, timer User-Agent: Media5-fone/4.1.6.3283 Android/4.1.2 Content-Length: 0 Path: <sip:outbound@10.18.130.46;lr;received=sip:client_pub_ip:5063%3Btransport%3Dtls> P-hint: outbound Slava From: "Daniel-Constantin Mierla" <miconda(a)gmail.com> To: "Slava Bendersky" <volga629(a)networklab.ca> Cc: "sr-users" <sr-users(a)lists.sip-router.org> Sent: Tuesday, March 3, 2015 1:50:03 AM Subject: Re: [SR-Users] kamailio asterisk Hello, I pushed a fix for it -- the issue was in a LM_DBG() trying to print te address for local socket, but it was not set yet, it was affecting only when running in debug mode with debug=3. I pushed the patch to branch 4.2, so if you want the fix, then you have to install from git branch 4.2. For REGISTER, you need to add the Path header (see path module), otherwise the OPTIONS and INVITE sent out to the phone are not going via Kamailio. You have to check the version of your Asterisk to be one that supports Path.

Kamailio as a SIP softphone to WebRTC/SIP-over-websockets proxy?
by Rion Carter 02 Mar '15

02 Mar '15

I'm pretty new to SIP, RTP/SRTP, WebRTC and Websockets, so I hope this question is coherent. I have a group of SIP Softphones that need to connect to a WebRTC/SIP-over-Websockets server. Can Kamailio be configured to let me do this? Any examples, tutorials or documentation would be appreciated. I'm trying to determine how feasible this task is. :) Thanks!

kamctl: command not available
by Thomas Baeumer 02 Mar '15

02 Mar '15

Hi there, I want to use kamctl to monitor the state of a sip-proxy. I just have no idea which commands are available or should i use "kamctl mi" or "kamctl fifo" commands. Google dont give helpful links for that. Im am using kamailio 4.2.3+wheezy on a Debian wheezy and kamctrl dont work: # kamctl fifo uptime Control engine 'FIFO' loaded entering fifo_cmd uptime 500 command 'uptime' not available FIFO command was: :uptime:kamailio_receiver_19959 # kamctl fifo which Control engine 'FIFO' loaded entering fifo_cmd which 500 command 'which' not available FIFO command was: :which:kamailio_receiver_19985 # kamctl mi which Control engine 'FIFO' loaded entering fifo_cmd which 500 command 'which' not available FIFO command was: :which:kamailio_receiver_20016 here is my config: # grep -i fifo kamailio.cfg loadmodule "mi_fifo.so" modparam("mi_fifo", "fifo_name", "/tmp/kamailio_fifo") modparam("mi_fifo", "fifo_user", "kamailio") modparam("mi_fifo", "fifo_mode", 0640) # ls -la /tmp/kam* srw-r----- 1 kamailio root 0 Feb 27 12:39 /tmp/kamailio_ctl prw-r----- 1 kamailio kamailio 0 Feb 27 14:25 /tmp/kamailio_fifo The only known command what is working is to look into a hashtable: # kamctl mi sht_dump foo Control engine 'FIFO' loaded entering fifo_cmd sht_dump foo Entry:: 135 sip:0049xxxxxxxxxxx@sip.domain.tld:: 1 Entry:: 205 sip:0049yyyyyyyyyyy@sip.domain.tld:: 1 FIFO command was: :sht_dump:kamailio_receiver_20144 foo any idea what is wrong? and is there a documentation how to use "kamcrl mi" and "kamctl fifo"? Thanks Thomas

Hello, sr-users is the mailing list more appropriate for such discussions that the docs. However, you wrote to -owner address which is not the mailing list discussions address but mailing list control address. For the topic, look at the readme of the websocket module, it gives a sample for starting with webrtc. On github (search for), Carlos Ruiz Diaz has some more advanced examples.
