call forward to forwarded user voice mail


we have ccm 6.1/ unity 5.1

we have a user [A],  that has their number forward/all to another user [B].

when caller dials A, and fwds to B who does not answer, caller goes into A vm greeting.

How can we make caller go into B vm instead.

i've tried changing the redirected number on the dn setting, but is still going to A vm.

Re: call forward to forwarded user voice mail

Hi Rob,

In Unity 5.x and above you can config Unity to use the "Last  Redirecting Number" on a Call Forward instead of the "Originally Dialed  Number"

You have to keep in mind that this is a "system-wide" setting

Route  Forwarded Calls by the First or Last Redirecting Number

Cisco Unity  supports the option of routing calls based on either the first or last  redirecting number when a call is forwarded to Cisco Unity.

Note the  following:

This  option requires Cisco Unity-CM TSP 8.1(2) or later.

This option  is not supported by integrations through PIMG units.

This option  can be changed through the Advanced Settings Tool (AST), which is  available in Tools Depot.

Call  Information Exchanged by the Phone System and Cisco Unity

The  phone system and Cisco Unity exchange call information to manage calls  and to make the integration features possible. With each call, the  following call information is typically passed between the phone system  and Cisco Unity:

The extension of the called party.

The  extension of the calling party (for internal calls) or the phone number  of the calling party (if it is an external call and the phone system  supports caller ID).

The reason for the forward (the extension is  busy, does not answer, or is set to forward all calls). There is also a  reason code for Direct Calls.

Cisco Unified Communications Manager SCCP  and SIP trunk integrations can also provide the following call  information (the choice of first and last redirecting number is set in  the Advanced Settings Tool, which is available in Tools Depot):

Called  number

First  redirecting number

Last redirecting number


Note  Cisco Unity can use either the first redirecting number or last  redirecting number, depending on the setting in the Advanced Settings  Tool, which is available in Tools Depot.
