Additional Comments
When dialing from an external phone (PSTN) to a PBX’s user extension, and the call is forwarded to
the voice mail (for any reason), and a voicemail is left to the PBX’s user, the following limitation
exists: The PBX doesn’t support caller-ID from external numbers and tags them as a call from 02222.
Therefore, "02222" is displayed in the sender field of the voicemail message for all external numbers
(PSTN).
Failure Point The Siemens HiPath 3550 PBX doesn’t support
invalid number notification.

Additional Comments
When performing blind transfer to an invalid number, the PBX doesn’t support invalid number
notification and the call is routed back to the original transfer user. When an invalid extension number
that's defined in the Microsoft Unified Messaging for a particular user, and a call transfer by Directory
Search to this user is requested, the user that requests this transfer is routed back to the Microsoft
Unified Messaging welcome prompt.
