Hi, is it possible for FS to take the callee codec from an interant call to external as reference ? example: userA (with only GSM) from FS calls whoeverUser@whateverdomain, this whoeverUser has only PCMU codec, so FS has a list of GSM,PCMU,PCMA and so starts to transcode from PCMU to GSM. I succeed to do the contrary (it transcodes from external to internal phone) Thanks Franck
