Re: Deny IP phone to the PSTN

Use partitions/calling search spaces.

There's plenty of info you can get from the cisco website about configuring this.


Re: Deny IP phone to the PSTN

You will restrict or allow different call patterns thru Partitions and Calling Search Space (CSS). Each route pattern that you define will be assigned a Partition. For example you might define the four digit dialing route pattern as 2XXX and assigned to the InternalPT. You might define local PSTN dialing as 9.[2-9]XXXXXX and assigned to the LocalPT. Then you might define long distance dialing as 9.1[2-9]XX[2-9]XXXXXX and assigned to the LDPT. Now you build your CSS and add the appropriate PT's. For example, for internal dialing only, you might build a CCS called InternalCSS and then add the InternalPT to this pattern. For local dialing you could build a CCS called LocalCSS and then add both InternalPT and LocalPT. For Long Distance you could build a LongDistCSS then add InternalPT, LocalPT and LDPT. Then on the phone you assign the appropriate your case you would assign the InternalCSS to restrict calls to the PSTN. If you want to allow calls to both internal and local PSTN then assign CSS = LocalCSS.

Hope that helps. Cisco Press has a book out called A Cisco AVVID Solution Cisco CallManager Fundamentals that explains all the above in much better detail.
