Call Restriction according to Calling Number on a SIP Trunk

[mesut ozcan]

Dear all,

There is a SIP Trunk between CUCM and Alcatel A4400 IP PBX. CUCM is using for IP Phones and Alcatel fo Dect Phones.

All calls between DEct and IP Phones go throug that SIP Trunk and that SIP Trunk's CSS is highest privilege CSS. I need this because CEO's assistance needs to call CEO with dect phone. But because of these CSS, a user like cafe or kitchen can call CEO from his dect phone also. It is not acceptable.

Is it possible to restrict call or give different CSS's on SIP Trunk according to CALLING number?

Maybe CEO and his assistance has highest privilege CSS and can call everybody but kitchens dect will have a small CSS and only can call internal number.

Waiting and need your helps.

Thank you,

Mesut

The calling privileges that you want to apply to your DECT phones will need to be configured on your Alcatel PABX.NOT on your SIP trunk, for the simple reason that you can only apply one CSS to your SIP trunk inbound and it cannot be tied to a calling phone partition.

Mesut,

There IS actually one way to do this, but I would recommend you spend a good amount of time reading the documentation. The feature is called Call Screening or "route next hop by calling number".

In my opinion, this is something you must be very comfortable with before implementing.
