CFwALL to voice mail


I have several users that would like to have their phones forwarded into another user?s voice mail. What I have found is that simply doing a CFwALL to the extension of their choice does forward the calls but the call comes back to the original user?s voice mail.

If however I CFwALL the phone to the other extension using a 9-xxx-xxxx and make it a local call it works.

Is this normal?

Re: CFwALL to voice mail

Hi Mike,

This is normal (the reason it works when you forward vix 9-xxx-xxxx) is that the CLID is stripped and is just like a normal incoming call to the second extension, if you are using most voicemail systems including Unity or Avaya voicemail this is working as expected.

There is hope coming in 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),(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;

If this is just a one-up type of setup you can configure a Voicemail profile (in CCM) for User B and apply it to User A that will allow this type of Call Forward to User B's mailbox.

Or in Unity set up Alternate Extensions so that User A is an Alternate Extension for User B etc. Sharing a Cisco Unity Voice Mail Box between Two or More IP Phones

Configure Alternate Extensions

Open the Unity System Administrator web page.

Navigate to the subscriber's profile. Select Subscribers > Find and Select a Subscriber > Enter Subscriber Information then click Find and click the Subscriber's name for the subscriber that owns the primary phone (Phone B).

When the subscriber page comes up, select the Alternate Extensions option and click Add.

Enter the alternate extension number (in this case Phone A) and click the Save icon.

From this good Unity doc;

Hope this helps! I'm still thinking about your previous question :)

Re: CFwALL to voice mail

Thanks Rob,

I have used the Alt ext in Unity for a user who had 2 phones/ext but one vm. this saves on a lic also.

Say, I tried the CFwALL with a long distance number and it came back to originators vm, it only works using the local number.
