Fail to adjust PTIME with OPUS

10 May 2016

      Hello,

I have an environment with debian 8 and freeswitch 1.6.7 installed from the fs repositories.
With this env my call were working fine, using opus codec.

But recently I deployed a new env, with the same configurations from the previous one but with freeswitch's new release 1.6.8, and my calls are failing after few seconds when adjusting PTIME as the following log shows:

[WARNING] switch_core_media.c:2567 [VBR]: Asynchronous PTIME supported, adjusting JB size. Remote PTIME changed from [20] to [40]
[DEBUG] switch_core_media.c:2988 Changing Codec from opus@20ms@48000hz to opus@40ms@48000hz
[DEBUG] mod_opus.c:661 Opus decoder stats: Frames[0] PLC[0] FEC[0]
[DEBUG] mod_opus.c:661 Opus decoder stats: Frames[0] PLC[0] FEC[0]
[WARNING] switch_core_codec.c:721 Codec opus Exists but not at the desired implementation. 48000hz 40ms 2ch
[ERR] switch_core_media.c:3025 Can't load codec?
[NOTICE] switch_core_media.c:3026 Hangup sofia/<profile>/<user>@<domain> [CS_EXCHANGE_MEDIA] [INCOMPATIBLE_DESTINATION]

Sometimes it successfully adjust few times before breaking, or breaks on the first try like this one.
It also happens with other PTIME combinations, like [40] to [80] or [20] to [60].

Is that an issue/bug?
Maybe related to https://freeswitch.org/jira/browse/FS-9062 that came with the last release.

Thanks
