we are using a UC500 with ISDN BRI Ports on small locations in Germany.
In normal scenario a call forwarding to an external number (i.e. Mobile) would be very easy configured.
A call coming in will be dialed out using a second line. But this will block two lines as long as the call lasts.
There is a special feature by the local provider (Telekom) regarding call forwarding on ISDN lines.
The forwarding is done by the providers switch, so not blocking any line at all. For this to activate you have to dial the following:
(The provider will respond with a message like "Activated")
To cancel the forwarding you have to dial
So, how can this be configured with the uc500 box (or call manager express)?
Any comments or hints appreciated.
