Re: [Freeswitch-users] Multifon -- Outgoing connection is broken after a few seconds (Sergey Zhuravlov)

It can still be described as unexpected by BYE from Multifon

The problem is solved by setting the parameter

<param name="rtcp-audio-interval-msec" value="5000"/>

 for profile external

Thanks to Vladimir from ros-tel

I think that there does not affect SIPALG
I tried another phone other tension, all the same, in fact tried through
CSIPSIMPLE and 4G - still
a few seconds, and normal conversation open

I'm guessing this is an insanely short and unreasonable media timeout on
their side coupled with a nat issue.  Check that the media ip is sane,
check of you have a sip alg on your side, if so, turn it off, sip algs are
almost all universally broken.  also look at a packet trace from outside
your router and see what is different.

Hi
Multifon service fron Megafon.
Outgoing connection is broken after a few seconds (~10) of conversation.
It seems the server provider sends BYE.
I can not understand the reason for such behavior and how to fix it.
Incoming calls through the same gateway works fine.
