Possible: 4-digit (internal) and 5-digit (external) dial

[mottelecom]

I have a Call Manager system (4.2) and I'm linking it to an Avaya system. I have the trunking setup, and incoming calls (from Avaya)are working great. Now, I need to setup 5 digit dial to the Avaya system. Is it possible to keep the 4-digit dial (internal calls) on the Cisco system, and add 5-digit extensions to route to the Avaya system? Having both 4 and 5 digit dial working simultaneously?

Any thoughts or can you point me in the right direction?

As long as they don't overlap yes you can.
If they do overlap you either have to change one of the two or introduce an access code when dialing the AVAYA to bypass the DN overlap.
