OK, so does that mean that setting it to 25000 should leave time for the re-invite or does the timeout start after that. If so is there another control for waiting for the re-invite? Note, a test by my provider shows that this particular number gives the re-invite after 6 seconds. I hang up at 4. -- D'Arcy J.M.

Pinging the list to see if anyone has any thoughts. Perhaps someone can explain what t38timeout is supposed to do as it seems to have no effect at all.

[asterisk-users] T-38 re-invite issue
I have an error sending to a specific fax number. It may be more than one but this is the one I investigated. It seems the delay for the SIP negotiation in T.38 was initiated after 6 seconds, however, our system sent the BYE after only 4 seconds, possibly cutting the call before all the communication necessary for the negotiation was completed. Here is the trace from our provider showing their successful call to the number and our failure.
