Hi All, Excited to see mention of T.38 passthru with 1.4.0.... BUT it seems like "Emperor's New Clothes" from my perspective. As I understand it, T.38 passthru only works via a re-invite mechanism - so two T.38 devices try talking fax and request a T.38 media stream. Asterisk is now savvy enough to realise it can't do it, so opts out - "Hey Guys, I don't know

Hello, We are trying to send faxes by T.38 protocol to a remote SIP proxy from a local extension. The local extension sends the INVITE, Asterisk sends the call to the Proxy the call is connected with a regular audio codec. After a few seconds the remote proxy sends an INVITE with UDPTL and the Asterisk sends it to the local extension and it's accepted, but (here the problem starts) just
