[OT] SIP on the Web
by Iñaki Baz Castillo 11 Oct '11

11 Oct '11

Hi folks, I would like to show a project my colleage José Luis Millán and me are working on. It's about SIP protocol running in a web browser. When RTCweb (media capable web browsers) becomes a reality both technologies together will allow real SIP endpoints coded in JavaScript running in a web browser and interoperating with real SIP networks. Bye bye Flash and custom protocol gateways. http://sip-on-the-web.aliax.net/ Cheers. -- Iñaki Baz Castillo <ibc(a)aliax.net>

releasing v3.2.0
by Daniel-Constantin Mierla 11 Oct '11

11 Oct '11

Hello, it is time to set the time to release v3.2.0. From my point of view, testing went very well, considering also that core and main modules were not touched much during this devel cycle, the most of the efforts were on new modules and application service components such as presence server, Lua ... A convenient date for me will be Tuesday, October 18, 2011, allowing to work a bit on packaging and docs. If there are other preferences, jump in this discussion.

Audio quality issue
by Austin Einter 10 Oct '11

10 Oct '11

Hi I am using Kamailio 3.1.5 . I am using RTP proxy also. I have used default kamailio.cfg.sample fiile , and just added line #!define WITH_NAT. I have another Main proxy. I wanted all my signalling and media packets should just pass through machine where Kamailio and RTP proxy are running. With this I found, call is established, all signalling and media packets are passing through kamailio / rtp-proxy. So far so good. One way audio stream (from called party to calling party) quality is good. The other audio stream (from calling party to called party is very bad. Did anybody face this issue? Please help me to sort out this issue audio quality issue. Regards Austin

Hi Just a quick question. How memory is allocated in Kamailio code. Few places I saw pkg_malloc function. Is it the only function used to allocate memory or there are similar functions present in kamailio. Thanks Austin

Kamailio RTP Proxy Questions
by Austin Einter 07 Oct '11

07 Oct '11

Hi I downloaded 3.1.5 Kamalio source, did make and install. Tried to run, and tested few basic scenarios, everything working fine. I have a main proxy, want to use kamailio as intermediate proxy and my requirement is all RTP packets should pass through machine in which Kamalio proxy is running. I beleive RTP Proxy I can run in same machine where Kamailio proxy is running with proper configuration . For this I am referring, http://nil.uniza.sk/sip/nat-fw/configuring-nat-traversal-using-kamailio-31-… page. In one of the steps it says "So, if we are using the Rtpproxy server with default configuration, we have to open /etc/default/rtpproxy file and uncomment following line regarding of udp socket, that will be sued for interconnection:". I tried to search rtpproxy configuration file, could not locate. While making and installing Kamalio proxy, the commands I used "make prefix=/usr/local/ all and make prefix=/usr/local/ install". Can somebody point me why rtpproxy config file is missing. Also the link I am refering to is correct or wrong one. Best Regards, Austin

Multiple INVITEs and discarded call_control
by Mino Haluz 07 Oct '11

07 Oct '11

Hi, my kamailio server is receiving from some customers 3 identical INVITEs when call is initiated (separated by 200ms). Those 3 INVITEs are making a big problem with call_control: WARNING: call_control [call_control.c:1156]: dialog to trace controlled call was not created. discarding callcontrol. That is why, the prepaid limit is not working at all in this case. This way the user can hack the prepaid protection of the account. Otherwise the call_control is fuilly functional. Anybody experienced the similar problem? If so, how to resolve it? Thanks, Mino Haluz
