No reply Local SDP after running for a while #313

Closed franktz closed 1 year ago

franktz commented 1 year ago

Hi. I'm facing a problem which has been bothering me for a long time. I use FS(mod_unimrcp) + unimrcp architecture, after running for a while(mod_unimrcp sends an offer with connection:existing to reuse an existing connection), unimrcpserver didn't reply Local SDP, and then FS close connection due to timeout and trigger Status 487 to unimrcpserver. Why no reply Local SDP after running for a while? Can anyone offer any suggestions that come to mind? Thanks.

Here is FS error log: 2022-10-20 10:30:40.370508 98.97% [ERR] mod_unimrcp.c:1914 (TTS-32564) SYNTHESIZER channel error!
