Hi all!We have a software company changing their iLBC codec so its working with asterisk - they had on 20ms and asterisk aparently is using the 30ms version.
They are complaning that the RTP I have just tested our new client in 30ms iLBC mode and it works against your PBX. I just have one quick question, I'm not sure if you are the correct person to be asking, but do you know why the PBX does not specify the iLBC configuration fully in the SDP sent? As per the iLBC specification, an extra "fmtp" attribute is needed to describe the mode you are working in, so that the other endpoint can negotiate or match it. The media part of your SDP message looks like this: .... m=audio 16040 RTP/AVP 97 8 3 0 101 a=rtpmap:97 iLBC/8000 a=rtpmap:8 PCMA/8000 a=rtpmap:3 GSM/8000 a=rtpmap:0 PCMU/8000 a=rtpmap:101 telephone-event/8000 a=fmtp:101 0-16 ... But it should have an extra a=fmtp line like this: a=fmtp:97 mode=30 as you are operating in 30ms mode. Is this someting anyone knows about, or is it fiexed in 1.2?
