Restricting PSTN Calls to one or two numbers

[noorudden]

Hi,

I would like to assign two PSTN numbers to be called from a specific DN.

For Example,

DN = 112 should only make calls to following numbers only.

+256700400100

+256700400101

Thanks in Advance,

Nooruddin

You don't mention what you use (always mention products you're working with and versions, not just what you want or your problem), so I'll assume this is with CUCM.

Configure those two numbers as exact route patterns in a special partition only that device will have in his CSS.

First of all 28xx routers are eol products 

A COR list can restrict the access 

Create a dial-peer with patters +25670040010[1,2]  assign it as per the documentation
