My understanding of the original posting is that when a voice call 
arrives from the SIP provider it includes T38 information though the 
user only wants to accept the g729 component of the call and carry out a 
voice conversation.

If a fax is being received by the SIP provider it only has a the T38 
information for the call thus no audio (g729) information is in the SIP 
message.

I don't believe the original poster is attempting to receive a 
facsimile, instead use voice calls.
