ptime in SDP - Need 20ms, getting 30 ms

[dlake02]

Hello

I am trying to make a connection to CallWithUs.  The ptime being sent in the Invite SDP is 30ms.  CWU inform me that they need to see 20 ms.

How do I change the default ptime for Yate ?  I've set all the iLBC codecs to ilbc20 instead of ilbc30, but still the ptime line is going out with ptime=30.

Please help !  This one is REALLY baffling me.

Disable ilbc30:
ysipchan.conf:
[codecs]
ilbc30=no

Keep in mind this will disable it for all calls.
