With the release of Cisco CallManager 3.2.2 spD, users have the ability
to transfer calls directly to a voice mailbox without ringing that user
extension, and without the need to navigate through any opening greetings. This
document details the configuration process.

Technical Tips Conventions for more information on document
If you use the configuration in this document, dialing an asterisk and
an extension drops the caller directly into the voice mail box that is
associated with that extension. This works by configuring a voice mail box mask
on the voice mail profile and associating it with a newly-created CTI route
point that matches against the asterisk. The asterisk gets stripped by the
voice mail box mask and the extension is placed in the Redirected Dialed Number
Identification Service (RDNIS) field before the call goes to voice mail.
Note: Use of an asterisk is not a requirement. The asterisk is used as an
example for the purposes of this document. You can use any distinct sequence of
numbers in place of the asterisk. The use of a special character like an
asterisk to begin the dialing sequence for this feature is often a good plan
because most standard dialing plans do not have patterns that begin with the
asterisk key. It is usually a good idea to preserve the use of numeric ranges
such as 0 through 9.
As this example shows, a new voice mail profile must be created. The
profile has been named TransferToVM in order to distinguish it from the voice
mail profile that is associated with user phones. The voice mail pilot should
be set to the currently configured pilot number. The voice mail box mask is
assigned the wildcard XXXXX to match a five-digit dialing plan. If four-digit
dialing is used, set this wildcard to XXXX.
Whatever the dialing plan, this wildcard matches the dialed digits
starting from the right. Anything that precedes the digits that are matched by
the mask is stripped.
Caution: Do not make this the default voice mail profile for the
You must create a new CTI route point. The example in this section
shows one named TransferToVM. This device is configured just like any other
with a device pool, calling search space, and location. This is a CTI route
point that will never be registered by any CTI application, and it should not
be associated to any users in the directory.
The configuration on the CTI route point line makes this all possible.
In this example, the Directory Number is set to *15XXX. This setting can just
as easily be *XXXXX to forward to all mail boxes, or something as granular as
*15654 to forward to just one user mailbox. Choose the voice mail profile that
you created in the section Configuration of the Voice
Mail Profile for the Voice Mail Profile field, and select
Forward All to voice mail under Call Forward and Pickup
Now anyone can call a user mailbox directly (or whoever's extension is
included in the CTI route point directory number). If there are multiple,
separate voice mail servers, such as an Octel and Cisco Unity system, you must
create a voice mail profile for each of them. You can use the same CTI route
point if you add extra lines. This even works across intercluster trunks.
Note: Do not use the word "Voicemail" as the Alerting Name or Display
(Internal Caller ID) for the CTI Route Point Defined. Use of the word
"Voicemail" can cause Cisco Unity to process the call as a Direct Call, instead
of processing it as a Forwarded call.
