CME FXS/DID Configuration Assistance

We have 4 DID trunks cross-connected to 2851 CME router running 4.1 When making an inbound call to a known DID number the port will light up, the call will hang, and go to a fast busy. I have tried all three different signaling types on the voice-port without success. The Telco is supposed to be passing 3 digits to which I am adding a zero on the end to correspond with internal extension numbers with a translation profile on the voice-port. the other numbers are begin translated to the AA number. Could anyone give me some ideas as to what is missing in my config or possible causes for the signaling problem?

All inbound dialing is to come in on the DID trunks and outbound dialing is set to FXO Pots lines.

Thank you for your time,

Melissa

Re: CME FXS/DID Configuration Assistance

Hi Melissa,

possibly it's a timing issue.

Can you take a "debug vpm signal" with "term mon" for the incoming DID call?

Please choose the signalling config that matches better what telco told you they have.

Thanks!
