[cisco-voip] T.37 onramp & voip dial-peer + back2back connection

[Robert Hass]

Hi

We migrated our Telco provider from E1 to VoIP (SIP). We used before T.37
on-ramp for receiving faxes to e-mail.  Unfortunately T.37 on-ramp needs
POTS dial-peer and it's not working with VoIP dial-peer.

In my router I have two port E1 card and I can connct both E1 ports
together (back to back) for passing traffic to fax number from voip dial
peer to pots dial peer.  Solution was proposed here
https://supportforums.cisco.com/thread/252378.  But I'm looking for
configuration guidance - how my dial-peers configuration should look.
