We have set directmedia=yes as well as directmedia=no.  There is no NAT involved.

Have you configured the canreinvite=yes in sip peer?

I am currently off work for two days, but a 100% fail means a configuration problem for sure.

	We are offering $100 (paid via paypal or check) to the first person who assists us in successfully sending and receiving faxes in the setup described below.  Offer expires Dec 31.  We are a direct customer of Level 3, there is no other carrier involved.
	
	What we want to work:
	
	    Level 3 T.38 TN <-> MSX/Nextone SBC <-> Asterisk 1.8.18.1 <-> Adtran NetVanta w/POTS and T.38 support.
	
	When we replace Asterisk with Kamailio faxes work fine.  When we put Asterisk there instead, then faxes fail nearly 100% of the time.
	
	I see the switch to T.38 in the Adtran debug logs.   We can originate and terminate T.38 calls in Asterisk using SendFax/ReceiveFax using T.38 so I'm assuming I have my udptl.conf and sip.conf settings correct.
