[cisco-voip] CallManager Handle Call Routing with PBX interoperability

Basically you'll need some type of voice gateway to receive calls  
from the PBX (via PRI or other physical link) and send them to the  
CM.     Once the call hits the CM it gets routed normally to a phone,  
route pattern, etc.

Dear All,

I have a question about the PBX interoperability with CCM. What can I  
do to make CCM to handle all the call routing even for the PBX end- 
phone?
One of the solution I heard about is to use SIP trunk connecting with  
CCM & PBX, but I'm not quite sure how to do that. Any suggestion or  
comment would be very grateful. Thanks.


Regards,

Alan
