Preventing a POTS diale peer making "offnet" calls

[tsalt]

I have a router with 8 analogue phones connected by FXS ports. We have a VoIP dial peer configured as 9T to a router that has the PBX connected allowing outside calls. So when a users wants to dial an outside line they prefix the number with a 9.

How can we stop a single extension (single POTS dial peer) from being able to dial 9 and making an outside call?

Many Thanks

Hi Tom,

You could create a dialpeer with the "answer-adress calling number" and translate this to any other number so that it would not match any voip dialpeer and would fail.

eg.

voice translation-profile voice

translate calling 1

voice translation-rule 1

rule 1 /9100/ /2000/

dial-peer voice 1 pots

answer-address 9100----depends on what the gateway gets.

translation-profile incoming voice

Then if you have a dialpeer for voip with destination pattern as 3... then it would not match and the calling party could not make an outbound call.

This may help you.

Thanks

You can use Class of Restriction feature to make this happen.

Thnaks for this. Our IOS does not support this facility at present. So as a temporary measure we have used the previous answer. Once we gett he routers upgraded then we will change to this.
