Note that on the re-INVITE (with SDP), sipX sends the ITSP all
supported codecs (including G729 - I need to filter this out but that
is a different problem ). The phone selects G711 and ITSP sends in
G711 in the period of time following Frame 46. This is legal ( the
ITSP answered with G711 and G729)  However, it appears that the
asymmetry of the media stream causes the observed problem of no speech
path. So there appears to be an ITSP issue at hand.

If I understand you correctly, the problem is that the ITSP sends an SDP answer 
listing 3 codecs, and then refuses to process RTP that is encoded in one of 
those 3 codecs?

Is there a reason we want to cooperate with such brokenness?  Couldn't this be 
solved far, far more simply by getting the ITSP to list in its SDP answer the 
one codec it was willing to process?
