#1 I assume you have spandsp installed

#2 I’m guessing you got some hints from this thread –

  • I was not aware you needed SpanDSP for T.38 passthrough.. How will that work with the UDPTL packets not going through Asterisk.

  • Not certain that you actually do. I do know that T.38 can be a “dental”
    experience with Asterisk, but some folks have succeeded with it.

  • We process a lot of t.38 with Level 3 and our Asterisk servers. We do not prefer Adtran end points for t.38.

  • Do you use faxdetect at all? I’m wondering if faxdetect is required for Asterisk to set CHANNEL(t38passthrough) to 1. It is set to zero on fax calls passing through Asterisk.
