HI Prabhu,

AS a broad overview to this scenario, solution could be like this.

CCM will have a gateway & the gateway will connect physically to PBX. Thus the topology would be CCM == Gateway Router === PBX.

This is how normally done when companies want to keep their old PBX also live while before migrating completely to IP Telephony.

By doing this, newly implemented IP phones can still talk to old PBX users & vice versa.

Hi Prabhu,

CallManager is capable of trunking with other systems via H.323 and SIP. What protocols does your EPBAX support?
