Unity Express Wan problem

Unanswered Question
Oct 16th, 2009

Hi all,

My problem is the CME or the unity express is dropping the call coming from the wan.

For calls from the PSTN or from the local network the unity is answering correctly.

Anybody know what could be the problem?

I will appreciate any help.

Are you using G711 for wan calls to CUE ?

Otherwise, you need to configure transcoding on the hosting CME.

but how this configuration should be done?

this is the dial-peer to unity

dial-peer voice 635555 voip

description To VoiceMail

destination-pattern 63555.

session protocol sipv2

session target ipv4:

dtmf-relay sip-notify

To begin with, can you ping ?

Then, take "debug ccsip message" with "term mon".

yes, the ping responding.

The debug I will post later because this can be only done in the non-business hours.
