CME not being able to call Alcatel PBX

Hi all,

I have the following issue, I have a CME at site A and an Alcatel PBX at site B. Alcatel phones can call the IP Cisco Phones. The IP Phones cannot call the Alcatel Phones, they get the following error 'Unknown number' and the 'beep beep beep' is heard.

Before that, the CME was installed in the same site/subnet as the Alcatel PBX (for testing purpose) and it was working fine both ways.

The routing is working fine between the 2 sites, you can ping both ways and access remotely both ways.

What could possibly be the problem?

Any help would be appreciated. Thank you.

Re: CME not being able to call Alcatel PBX

Likely, either CME or PBX are missing correct routing information (default).
