How to: IP Telephony, making anonymous calls, withhold outgoing number

[Vincenzaccio]

I am using an IP telephone in the Cisco 6900 range, in the UK.

How do I withhold my out-going number, selectively?  On a normal BT domestic telephone line, I prefix the number I am dialing with 141.

I want to do this selectively.  I don't want the exchange administrator to make all my outgoing calls anonymous.

Hi Vin,

You need to configure a new route pattern to allow the system to identify the call. E.g. if you prefix 9 for external calls then you would have a router pattern 9.@. If you add a new pattern for 9141.@ you can then set the Calling Line ID to ‘Restricted’ on this route pattern.

Hope that helps.

Hi,

You will need a route pattern and or dial peers to match the code you are dailling.

E.g.

91410XXXXXXXXXX point to route list/group/gateway

And/or

a dial peer like:-

dial-peer voice 9141 pots

desc *** WITHHOLD CLI ***

destination-pattern 9141T

progress_ind setup enable 3

progress_ind alert enable 8

progress_ind progress enable 8

progress_ind connect enable 8

direct-inward-dial

prefix 141

port 0/0/0:15

!
