[Freeswitch-users] Can't restablish media

[Javier Gallart]

Hello

I was wondering if someone has experienced this situation. I have a call
with bypass_media=true; and this call fails with cause 488. I catch that
faliure in a lua script where i set bypass_media=false and change the codec
via the variable absolute_codec_string, expecting the Sangoma D500 takes
care of the trasncoding . This second call is successful, however when  a
183 is received at the b-leg, I see this debug message at the console:

2013-01-15 17:24:27.489568 [ERR] switch_ivr.c:1487 Can't re-establsh media
on sofia/internal/xxxxxx at y.y.y.y

The 183 message is absorbed by  FS, and there is no media transmitted back
to a-leg (therefore no ringback heared). However the 200 OK is correctly
transmitted, and the calls works apparently works fine. Any idea?

This happens at least  with Freeswitch versions 1.2.1, 1.2.3 and 1.2.5.3

Thanks in advance

Javi
