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@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
