Restrict FXO line

[SwathyEdayath]

Hi ,

We have two fxo lines . is it possible to restrict one of the line usage only among two people . and another one common for all .

we are running cucm 11.X version.

Yes you can do this. Depending on what protocol you are using to connect CUCM with voice gateway.

For example, if you connect to gateway using SIP trunk.

1. On your gateway create cor-lists for FXO_1 and cor-list for FXO_2

2. Create dial-peers to match calls from two people using answer-address

3. Assign cor-list FXO_1 to this dial-peer.

4. Create outgoing dial-peer out of FXO Port 1 and assign the corresponding cor-list to it.

5. Create dial-peer to match calls from rest of people and assign cor-list FXO_2 to this dial-peer

6. Create outgoing dial-peer out of FXO Port 2 and assign the corresponding cor-list to it.

Here is a document on how to create cor-lists

Hi Mohammed,

Thank you for replying . we have h.323 gateway .attached is the configuration done for the gateway .

fxo line on port 0/0/1 is for everyone and port 0/0/0 is only for GM and his PA.

Yes you can use the same steps as described above.
