Cisco CME: Reserve an outgoing FXO port for a group of internal extension?

[Nhan Ho]

Hi Experts,

I just came across a situation where a client required that a particular PSTN line (that is connecting to FXO 0 on a CME, for example) is reserved for outgoing calls for a small group of internal extensions (let's say it's 8010 to 8019). I did some research but could not find anything relevant.

Could anyone please help me by showing me whether it's possible to do with a Cisco CME? If so, what is the feature called?

Thank you very much in advanced for your time and for sharing your wisdom.

Regards,
Nhan.

Hi

You'll need cor list like this

dial-peer cor custom

name pt-internal

name pr-external

dial-peer cor list css-internal

member pt-internal

dial-peer cor list css-external

member pt-external

dial-peer voice 9 pots

destination-pattern 9[2-9]......

corlist out css-external

...

ephone-dn 1

number 8010

corlist incoming css-internal

ephone-dn 2

number 8019

corlist incoming css-internal

Here, this is a little easier to understand. I have it setup so that extension 2001 will always use FXO port 2/1 for outgoing calls and extension 2002 will always use FXO port 2/0 for outgoing calls.
