Selectively block CLID for outbound calls

[Christopher Liesfield]

Hi All. We have a situation wherein we need to block CLID for all outbound calls globally, except for when the called party matches a certain range of numbers.

We are located in Australia.

Is this possible?

How would we achieve this?

Thanks in advance.

Start by mentioning the products you use, version, and call flow, not just what you want to achieve.

Regarding our environment:-

- CUCM 11.5(1)(SU7)

- 3945s on 156-3.M2, E1s (ISDN) for voice services, configured as SIP trunks in CUCM.

- Calls made from 7924, 8811 series handsets, Jabber, etc, outbound to the PSTN via aforementioned 3945s.

Please advise if you require more information and thanks in advance for your help.

Assuming you configured the calling party to restricted in CUCM in the route pattern, you only need to create new RPs that are a better match than the one that blocks the calling party and allow the calling party info.
