Is there any good way to have inbound Fax and Voice calls use the same DID?
I know there used to be a Fax Onramp TCL script, but I thought that was for TDM circuits (T1-PRI).
In this scenario, the PSTN comes from a SIP provider to a CUBE router. The provider does support T.38.
Call flow is: Remote Fax machine -> PSTN -> SIP Provider -> CUBE ->SIP -> CUCM (or Fax server.)
Ideally, I would like to send Fax calls directly to a 3rd party Fax server without going through CallManager (using dial-peers).
I'm hoping there is some secret SDP message that says "This is a Fax call, route me to the Fax server".
