Redirect Calls Based on Calling Party Number

[jerold.baker]

Hi All,

I am looking for a method to redirect inbound PSTN calls based on the calling party number.  I can do this in CUCM 9 or IOS.  I find plenty of documentation out there on blocking calls by calling party number but nothing on redirecting.     

My situation is this.  We are a large company and often get request from users to block calls from annoying or harassing numbers.  Rather than block them I would like to drive them into a mailbox where the caller can attempt to find a resolution if they feel the calls was blocked in error.

Has anyone else attempted something like this? 

Thanks

Hi,

There's no way to route based on calling party number in CUCM.

Probably you can configure a voice translation-rule in the gateway (needs to be H.323 or SIP, not MGCP) that matches on the caller-id and translates to something that will route the call to the DN you want.

Regards, 

Tere.

Thanks Tere,

My thinking was along the same lines as yours.  It would need to be done in IOS on our H.323 gateways.  I just have not found a way to change the called party number basied on the calling party number.  Call Rejects are easy but they also create a blackhole that things fall into.

Hi Jerold,

If you are using CUCM 8.x and above, you can re-direct the call on the basis of the calling party number.

The configuration is very similar to block a call that uses the new feature added in CUCM 8.x and above (

Route Next Hop By Calling Party Number). The step 8 in the following document explains how to handle the call when the call has be routed by the calling party number. The translation pattern is configure with Route Option as "Block this pattern".

In order to re-direct the call, you can configure the Route Option with "Route this pattern" and specify the desired destination pattern under "Called party Transformation Mask". Also, make sure to add the appropriate CSS to be able to route the call.

HTH,
