Route by Redirection

The method "Route by Redirection" allows that all the users can use the same voice mail number (voice pilot number) and nevertheless have their individual voice box. Because of this, this number can be entered in the PBX globally as "dropping number".

Moreover, all the users can call this number from their office telephone in order to access their mailbox by telephone.

If available, a key for the call-back to the mailbox can be configured in the PBX globally.



As "voice mail number", the number 9999 has been determined. The PBX routes all the calls to this number to the ixi-UMS Business Kernel.


A user switches the call transfer at his telephone to the number 9999. When a call comes in at the user's phone, this call is transferred to 9999.

The ixi-UMS Business server accepts the call, but evaluates the originally dialed number, the telephone number, and searches for this telephone number in the specified LDAP database. When user is found to this number, the deposited announcement is played. The caller can leave a message, which is sent to the mail server and then to the mailbox of the user.

The user can access this voice-maiboxl e.g. by calling the number 9999 from his office telephone. He then is connected to his mailbox immediately.


Set up ixi-UMS Business

In order to set up "Route by Redirection" on the ixi-UMS Business system, the following steps have to be taken:


1) ixi-UMS Business must be enabled for the evaluation under "Voice-Mailbox" - Basic Settings - Shared Voice-mailbox number and the future global number must be specified.


2) The Welcome Mail must contain the valid "Voice-mailbox number" for all users.


3) The telephone number of the forwarding telephone must be entered in the LDAP database with the user in the format: +49 956 8411288 or +499568411288 in the fields:

§TelephoneNumber (telephone number) or

§OthetelephoneNumber (phone number - other).


Determine the required numbers

"Route by Redirection" can only be used when the PBX forwards the actually dialed phone number as RedirectionNumber (or Diversion Number / diversion leg info with QSIG).

In addition, it must be ensured that when using "E.164" also this call number is transmitted as E.164 call number.


In the following tests, please note that the ixi-UMS kernel service must be terminated.

If the tests are completed after the base configuration is complete, you must open the Windows Services console and stop the ixi-UMS Business Server service.
