Long Distance Call Restriction

[Grayson Wells]

What is the best way to restrict who can make long distance phone calls? I thought about enabling the long distance route for forced authorization codes, but I would really rather specify certain phones that are and are not allowed to make calls. The reason I want to do this is because it is the way it is done with the PTSN phones. So when users migrate to the IP phones I want them to still have the same restrictions.

Hi Robert,

In CUCM this is accomplished via the configuration of Partitions and

Calling Search Spaces (CSS)

Hi Rob,

you can do the following,

you can have three route patterns

r1 (long distance)

r2 (local calls)

r3 (internal calls)

r1-->Partition r1

r2-->Partition r2

r3-->Partition r3

A calling search space comprises an ordered list of partitions that users can look at before  users are allowed to place a call. Calling search spaces determine the  partitions that calling devices, including IP phones, softphones, and  gateways, can search when attempting to complete a call.

PhoneA capable of of making all three types of calls.

PhoneB capable of making local and long distance.

PhoneC capable of making only internal calls.

so PhoneA CSS would contain partition r1, r2 r3

PhoneB CSS would contain partition  r2 r3

PhoneC CSS would contain partition  r3

Hope this helps.

So partitions 1, 2, and 3 would be in the same calling search space? That would make sense because there are some phones that need to have access to all three routes. But that assumes that you can specify what partitions a particular phone has access to. How do you do that?

Robert,

This is a bit simplistic but gives the idea.

Apply the correct level of CSS access to the lines

Only give the phones CSS access of CS-PHONES-ONLY

I have used "9" as the external access digit

PA-911-EM

PA-PHONES

PA-LOCAL

PA-NATIONAL-LD

PA-INTERNATIONAL

Hi Robert,

You control what partitions the phones can access using the CSS. A CSS is simply a list of partitions.

We use the country numbering plan (http://www.cisco.com/en/US/docs/voice_ip_comm/cucm/idp/504_423/deploy/dpDlPlns.html) and define route filters to control access to certain types of numbers. We tie the filers to individual partitions then build up a CSS for different users groups.

Hope that helps!
