[Freeswitch-users] Record write part of all legs in a bridge call

Wed Jul 31 19:35:36 MSD 2013

If you're getting identical records then most likely there is a glitch in
how the record_session app is being called, i.e. it seems to be getting set
twice on the same leg. Can you re-post your configs and a call log to
pastebin?
