CME 4.1 on C2801 - using external voicebox

Unanswered Question
May 25th, 2007


I have a little problem with the usage of an external voicebox and CME 4.1!

We use 7941 phones and C2801 with CME 4.1.

Our provider (1x BRI) is T-COM (Deutsche Telekom) and all works fine.

In the switching center of T-COM there is a voicebox called T-NET-BOX.

If I do CFA with an ISDN-Phone to the Boxnumber 0800...... - incoming calls go to the voicebox of the T-NET-BOX!

If I do CFA on the IP-Phones to the 0800.... number - the incoming caller hears the prompt "Please input your pin" etc., like I call from my number the box to receive new voicecalls!

Whats wrong?

Are there commands on the 2801 for these ISDN-features?

The same "Input PIN etc." !!!

My Phone always transmits my own number, on such ISDN connections there is no "CLIP no screening"

I think I have to tell the ISDN my own number (the ISDN identifies my own voiceboxaccount) and the calling number (the ISDN identifies an external caller) who wants to speak on my box!

But I think the calling number is not trasmitted!

Actually the problem is original called party. Your voicemail thinks its the OCP whereas the extension is.

I'd open a tac case at this point because I'm not sure how you can mask your extension like you would in CallManager with voicemail profiles.
