Hi,

I am getting problem with gafachi T38
Service.

by seeing sip messages I found the following three type of errors.

1. gafachi send T38 re-invite before answer (here our Callweaver reject
this invite with "Loop Detected")

2. No T38 re-invite at all

3. SIP and T38 re-invite is ok. but after starting udptl call droped
with error 

Please help me to solve this problem.

Call log attached.

Regards
