We are using Cisco call manger 4.2 for IP telephony. Now we are also going to install Alcatel Lucent EPBX (OMNI PCX) in our office. Now my question: is it possible to configure Cisco call manger so that Cisco IP phone users can call to EPBX (Alcatel) users and vice versa.
Is it possible to use Alcatel Lucent EPBX (OMNI PCX) as a backup device for Cisco call manager?
You should be able to create some sort of a trunk between the two. If it's an ip phone system, you should be able to setup an h323 or sip trunk between the two without a problem. Then it's just a matter of creating route patterns to send traffic to the other switch. Not knowing anything about the epbx, I can't say if it can register cisco phones with sccp or sip, but I would say it's probably more work than it's worth to have them fail over to a different pbx. You would have to maintain two full configs for that to work. Are you switching from Cisco, or running both?
