Hi I am trying to setup a Unified Messgaing server connected to the iDCS500. This would be for Fax and Voicemail (obviously external).

The way in which we connect to other PBX's is using ISDN BRI S0's and Eicon ISDN cards. An extension range is normally assigned to the ISDN lines which are placed into a line bundle or group to allow hunting over all the lines. As such, the end result is each user has a physical extension (handset device)and a messaging box extension number ie 2 numbers. A call forward no answer is applied to the phone forwarding to the second messaging number. This is routed down the S0 to the UMS server giving DID digits (messaging number) and CLI digits (original caller). The UMS server will then answer with the user details.

The technicians that I am working with say that this is not really possible on the Samsung.

Please can somebody explain the way in which it should be setup. Thanks
