[asterisk-users] $100 Bounty: Level3/Asterisk/Adtran T.38 Pass-through

[Eric Wieling]

We are using t38pt_udptl=yes,redundancy,maxdatagram=400   Without the maxdatagram we get errors in the CLI.  We also tried using FEC instead of redundancy, but no difference.

Last thing to check, just for sanity's sake:

t38pt_udptl=yes in sip.conf? It defaults to off.

	It does not appear to make any difference.  Calls are still failing.

	True, but it should bypass Asterisk when possible for SIP streams and may solve your problem.

	        We have directrtpsetup=no because the comments in the sample config indicates it does not work in all situations.

	                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.
