As RFC4566 told us
The purpose of SDP is to convey information about media streams in
multimedia sessions to allow the recipients of a session description
to participate in the session
So if an UAC (alice )sends an SIP-INVITE with let's say g711u and an packetization time of 70ms the receiver (Bob)should only accept the call if it can handle that ptime and should also use the same. Otherwise the INVITE should be declined with 488 Not Acceptable.
But many UAC's (Bob's) whould answer this call with ptime 20 (or its default). A good UAC can react and use the ptime in Bob's 200 OK. Others don't , so both Endpoint use diffret packetization times.
Now I wanted to check out how yate behave in the middle of these szenarios.
My questions for now are:
How can I change the ptime in regexroute or routing module ?
How can I make yate respect the ptime send by the caller ? (i uses alway its default)
