CM4.2.3 and UM4.2.1 - Call Forwarding and VM

Hi

CM4.2.3sr1 with UM4.2.1

pstn calls 1000 which does a CFAll to 2000 which does a CFBusy/CFNoAnswer to VM but it always reaches 1000 VM. I want it to reach 2000 VM.

Unity's CallViewer always show 1000 as the forwarding DN.

I've tried:

1. Putting TP to change 1000

2. Diff combo of "Redirecting Number" "Called number" in phone config

3. Use the *2000 in the forwarding CFAll field which is my direct to VM

The only solution was to use Alt Ext in Unity but that is a per user config which I want to avoid as I want a global change

Re: CM4.2.3 and UM4.2.1 - Call Forwarding and VM

Hi Anthony;

This is normal, if you are using most voicemail systems including Unity or Avaya voicemail this is working as expected. The problem lies in the fact that Unity sees the First Redirecting or Originally Dialed number (User A's CLID rather than the Last Redirecting Number (User B's).

There is a fix in recently released Unity 5.0 though :)

Have a look at Michael's great posts, there is a fix on the horizon for this exact problem in (Unity 5.0) **now released,(ECSBU Test Engineer, CISCO SYSTEMS )

"The situation you describe here (getting Unity to recognize the last forwarding station rather than the first forwarding station), will be a system-wide option added to Unity 5.0. There is not a way to do this with a configuration setting on earlier versions of Unity. I'm not aware of any CallManager settings that will address this issue either."

"We use the OriginalCalledParty and OriginalCdpnRedirectReason fields in SCCP StationCallInfo message from CallManager. The feature in Unity 5.0 will allow admin to configure Unity to look at LastRedirectingParty and LastRedirectingReason fields instead, on a system-wide basis."

From this recent thread;

Also, here is another reference to this exact question with an answer from THE Unity Guru Jeff Lindborg;

Here are the Unity 5.0 release notes;

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.

Hope this helps!
