I lodged a fault report and received the following advice:
Please use the following code via your VOIP service in order to activate call forwarding from the server.
Dial 0110 - Disable call forwarding
Dial 0111X - Enable call forwarding (having X as destination number)
Dial 0140X - Set the timeout ring (having X in seconds, max 50 seconds allowed)
I have followed this procedure and... it works...thanks...
Perhaps a few words on the VOIP page in user facilities to notify users of the changed system would save a lot of wasted time with fault tickets
