The variable is sip_execute_on_image

Hello,

I'm trying to get T38 gatewaying to work. I have a call coming in with FAX audio, and an endpoint that needs T38. The endpoint will send a T38 re-invite, to which FS responds 100 trying, and after 40 seconds the endpoint will give up (citing stale 100 trying).

I set these variables before briding:

<action application="set" data="fax_enable_t38=true"/>

<action application="set" data="fax_enable_t38_request=true"/>

And then I bridge like this (dialstring is sofia/profile/number@ip:port):

<action application="bridge" data="{execute_on_image=t38_gateway self nocng}${dialstring}"/>

I've tried all variants I can think of, and always have the same result, except for when fax_enable_t38 = false, in which case FS rejects the re-invite.

I found some old discussions on the mailing list alluding to the same problem, but not much in the way of solutions.

Can anybody give me a pointer as to what I'm doing wrong? I was running a git clone from 1.2.2, but I upgraded to latest stable (1.2.7) with the same results.

Here's what happens in FS. At the very end you can see the Re-INVITE, and then nothing happens post that point.
