Control Access to voice port in CME

[t_kilany_2]

Hi,

Is it possible to configure an FXO voice port to be exclusive used by a user or a group of users?

Thanks

Tarik,

This is possible to implement in multiple ways. I will proceed with explaining the two that are most common:

1) Port segregation based on dialed number: You create POTS dial-peers with specific destination patterns, and assign the appropriate FXO ports.

Example:

!

dial-peer voice 5500 pots

destination-pattern 8.T

voice-port 0/0/0

!

This dial peers is accessible to anyone, so you would only give the dial string to the corresponding users (you would ask them to always dial the prefix "8")

2) A more secure, convenient way of doing this is using Class of Restriction, which effectively achieves dial plan partitioning.

Example:

!

dial-peer cor custom

name FXO

!

dial-peer cor list FXO-Only

member FXO

!

dial-peer voice 5500 pots

destination-patter 9.T

voice-port 0/0/0

corlist outgoing FXO-Only

!

ephone-dn 1

number 201

description Joe Doe

corlist incoming FXO-Only

!

To add to Marcos's comments...

Here is how you configure COR list.

Hi,

I wanted to add to the good advise you received from two experts (Marcos and Steven) with a way to group some FXO ports in a trunk group and some others in another, and then assign the PSTN Trunk Group to the outgoing dial plan access codes you desire..    Oh and did I mention you can do this all with CCA 2.1?
