I'm testing the t.38 code.

My test results from a Sipura 2100 --> Asterisk --> Lucent APX t.38 
gateway --> PSTN:

1.2.4 with t.38 patch -- asterisk detects t.38 sdp offering, then 
promptly sends some kind of corrupt data that crashes the ethernet card 
on my apx [wtf?]

1.2.7.1 with t.38 patch -- sip show settings and sip show peer xxx shows 
that t.38 udptl support is on, but asterisk never detects t.38 sdp 
offering.

team/group/t38passthrough SVN -- same as 1.2.7.1, asterisk never detects 
t.38 sdp offering

I would really like to get this working, I would be willing to pay 
handsomely via paypal for some assistance to get this to work. :)

yours,
Matthew
