Re: [SR-Users] Getting 404 From Kamailio for PRACK
by DanB 24 May '15

24 May '15

Hi Austin, Kamailio will not reject by himself (nor handle) PRACK (or any other methods) unless you tell him so. The logic for handling it should be in your .cfg file. I suggest adding xlog statements through your config script and see where that is rejected. 404 would tell me you are trying to locate your endpoint and send the PRACK there but the endpoint is not registered.

Re: [SR-Users] Increase Simultaneous Registration
by DanB 24 May '15

Hi Austin, Kamailio should be pretty fast on these things. Here are things which you can check: * Increase number of TCP workers/make sure you are using async TCP. * Use in-memory store for your registrations, not DB ones (at least dump async your contacts in DB). * Make sure you allow enough files to be opened in case of TCP connections (I suspect this is your issue there). Regarding performance tests, not sure if you saw already these links: http://www.kamailio.org/docs/openser-… [View More]

Find if client is connected.
by Dmytro Bogovych 22 May '15

22 May '15

Greetings. I want to modify INVITE answers processing in this way: 1) receive INVITE answer 2) check if recipient is registered but has no TCP/TLS connection now 3) suspend answer for 30 seconds (for example) 4) resume answer if REGISTER comes from lost client in these 30 seconds 5) terminate INVITE session if 30 seconds are expired What I do not understand - is it possible to find if client is connected now to kamailio? I talk about TCP/TLS connection only - not about registration record. Thank you!

issues with domain names in the record route
by NITESH BANSAL 22 May '15

22 May '15

Hello, I am trying to play with domain names in the Record-Route header. This is for a case when kamailio is doing the translation between UDP and TLS, so it is doing double record routing. I want to use the ip addresses on inbound UDP leg and domain names on the outbound TLS leg in record-route headers. I'm doing this by calling the following function -- record_route_preset("xyz.com;transport=tls", "1.1.1.1"); ---- This does the trick of adding a Record-Route in initial TLS invite on the … [View More]

Hi! I just found out that there is a new rtpproxy release: http://www.rtpproxy.org/post/v2release/ Has anybody tested it and want to share some experiences? Or have people turned to rtpengine meanwhile? (I am still using rtpproxy 1.2 as I do not need new features). regards Klaus

Clear To-tag on '181 Call Is Being Forwarded'
by John Murray 21 May '15

21 May '15

Hello, I am forwarding an incoming call to a destination and on time-out forward to another and them another. I need to send a '181 Call Is Being Forwarded' to my SBC to reset the early media stream when forwarding to the next destiation which I can do with sl_send_reply("181","Call Is Being Forwarded"). However the SBC vendor requires that the To-tag in the 181 is cleared for this to work. How can I clear the To-tag from this 181 response? Thanks John
