When inbound route has call recording set to "Record Immediately" recording file is missing any info about callerid or extension dialed. Example fille looks like:
force-5010-unknown-20140821-084718-1408628838.1090.wav (when extension called directly - 5010 is my incoming DID set in inbound route)
force-5010-unknown-20140821-084834-1408628914.1092.wav (when called through ring group)
and when recording is set to "Record on Answer" file looks as it should:
exten-996-3125027494-20140821-084511-1408628698.1077.wav (when extension called directly)
rg-100-3125027494-20140821-084615-1408628766.1083.wav (when called through ring group)
It's issue when you archive recordings and need to find something later. No way to do it without seeing incoming number or extension.
