To FreeSWITCH Users, I am just looking for confirmation of the following: 1. If I receive an inbound call to FreeSWITCH (the codec is negotiated and the call is answered by FreeSWITCH) and there is NO call bridging done, then am I correct that only the read_codec & read_rate channel variables apply (for CDR purposes)? 1. If I make an outbound call from FreeSWITCH (using originate api command) and once again there is NO call bridging done, then am I correct that only the write_codec & write_rate channel variables apply (for CDR purposes)? 1. When using mod_conference (for conferencing two inbound calls together or one inbound and one outbound (using originate api command) together) does this affect the read_codec & read_rate and write_codec & write_rate channel variables in any way? The reason I ask this is I noticed the following on an outbound call made (using the originate api command) recently and wanted to better understand what the read_codec & read_rate are used for when NO call bridging is done: read_codec: L16 read_rate: 8000 write_codec: PCMA write_rate: 8000 I appreciate the clarification.
