I am just setting up Fax Pro for the first time. Created Outbound and Inbound routes. Im using SipStation…T.38 approved DID… T38 turned on in SipStation My Account settings.
T.38 Enabled in Asterisk Sip Settings
Global Route Prefix set to *323
Sending in UCP fails… Says “The Call Dropped Prematurely.”
I can receive faxs no problem. Any help on what I have setup wrong ?
