[Freeswitch-users] audo sync issues with record_session to mp3

[John]

I've just enabled session recording using MP3 encoding and have the same 
symptoms.  In my case it is between a BRI ISDN connection and a SIP 
phone, both running with G.711.  I haven't tried recording between 
extensions which would be a purer test, nor have I attempted using WAV.  
Are there any suggestions for how to fix this? Should I register a bug 
on Jira?
