E1 Interface on TE Mode

Unanswered Question
Jan 4th, 2010


I have CME in one of our office location with SIP based Connection over internet with a E1 output ( SIP GW box ) to the Cisco router.

The SIP provider is asking me to configure the Cisco E1 card in TE mode, How do i configure that.

Please help!

You are sending out the same incoming call.

You must configure so that 932417563 rings somewhere, an ephone-dn or what you want.
