Unable to use Janus Sip Gateway with Asterisk

[Damien Fétis]

Hi all,

I'm trying to test last Git version of Janus SIP gateway with my asterisk-11 server and i'can't make a call from the demo application.

Other demo appplication like MCU and echo are running perfectly but not the sip gateway .....

When I try a call to an astersik extention, the REGISTER messages are OK but it's like astersik doesn't see the invite from janus.

I did some tcpdump on my Asterisk and i got this on the invite execution :

The INIVITE request part seems to be missing :

Does someone see that already ?

Hi Damien,

that's really weird... I just tried with the latest version with Asterisk 11.11.0 and it works fine for me, so I don't think there was any regression in the SIP plugin recently. I don't think anyone submitted any similar issue on github either. Have you tried doing a wireshark/tcpdump on the Janus machine as well?

Hi lorenzo,

thanks for your response.

I did a tcpdump on the janus machine and it's same the same resut..

But I found what cause this trouble in sip stack
.
For testing Janus gateway, I made a fresh linux install with lastest Fedora ( Fedora 20) and i install all required package by yum.
 
But there  are some bugs in Sofia-sip build in Fedora-20 du to GCC 4.8 optimisation (https://www.mail-archive.com/sofia-s...@lists.sourceforge.net/msg04563.html).

After rebuilding sofia-sip with -O0 options sip calls from janus to astersik work !!!!

Now I can continue to test Janus.

Good to know it works now, and thanks for the reference to the solution! I'm still on Fedora 18, which explains why I wasn't experiencing this. Let's hope they'll fix the package in the repository soon enough.

It's a known issue of compiling the Sofia SIP library on distros with gcc >= 4.8, you need to compile it with a patch applied (something that CentoOS repo managers should do themselves, if you installed it via yum). More info here:
