asterisk users - Mar 2006 - a=fmtp:18 annexb=no

Hello

Looking the SIP debug we see a change in the SETUP
message from the Asterisk 1.0.x version to the 1.2.4.
In the 1.2.4 we notice this line:

	a=fmtp:18 annexb=no

This line cause problems in our plattform (We think
our SIP -> h323 gateway can't parse this line)

Why this line its present in 1.2.4 version?
Have anybody some clue?

 
Regards

JS.
