Call forward all - last redirecting number and Unity

Is there a way on Unity 4.2.1 to use the last redirecting number instead of the first redirecting number? If not, is there a setting in CallManager 5.x that will send the call as the last redirecting number?

I have a situation where a phone (A) forwards all calls to a CTI Rt Pt (B) which forwards all to Unity. The DN of phone A comes into Unity (as seen in Call Viewer) and callers, of course, get A's greeting instead of B's greeting.

Any other way around this, where callers can hear B's greeting? Thanks.

unfortunately no, Unity 5.X does have this capability but no previous version.

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.

Try this is this will work.

Create a Voicemail Profile for this CTI Route Point (B) with the same voicemail pilot but on the Voice Mail Box Mask put the DN of the CTI Route Point (B) then apply this voicemail profile in the DN of the CTI Route Point (B). Test it and let me know if this helps.

Thanks for the suggestion. However, the customer closed the case so I can't do anymore testing.

It's an interesting work around. Wouldn't Unity still look at the "firstredirectnumber" field in the call though?

This will be the call flow

>Phone A x1000

> CFwd to CTIRtPt B x2000 (x1000 still present as the Firstredirectnumber)

> CFwdAll to Unity with VMProfile Mask to x2000 (from this point the x1000 then change to x2000 before reach the unity because of the Voicemail Profile Mask)

>The unity then see x2000 and play the greeting
