I'm getting an INVITE from the Cisco softswitch looking like this (from sip
debug trace):

This error makes the resulting call have no audio. Does anyone know what
this codec problem is? It seems like the extra /1 on the m= line is
different but I have no idea what that is supposed to be telling me.
Thanks for any help,
Bill Hamlin
