Using Router to extend pabx extensions

[BillB66]

I have to extend 2 analog extensions from a pabx using a Router with FXO ports. I am planning on connecting the 2 extensions to the FXO ports and then plar'ing them to 2 seperate IP handsets at a remote site. I have no problem with this portion , when I ring extension 111 it rings on the first Ip handset and when I ring ext 112 it rings on the second.

What I need to do is limit each handset to only be able to use its corresponding FXO port . Ie all calls from IP handset 1 must go out via ext 111 , including those to the other IP handset.

setup is like this
ext 111 - voice-port 0/2/0 - plar to 211
ext 112 - voice-port 0/2/1 - plar to 212

Can I nail down each ephone to only be able to use its corresponding voice-port ?

You will need to create separate route groups for each user and use specific route patterns that point to those route groups for each ip phone.
You will also need to create partitions for each user that needs that and assign it to their CSS.
