I have a client that uses a 7960 handset as an operator console, when the site goes into SRST mode the main number is presented to the 7960 handset. Any further calls to the same DDI number receive busy signal. Is there a way to queue calls on the handset. I have also tried forward on busy to a range of number but the forwarding does not take place, i can only get forward on busy to work if I'm specific with the extension number configured. For example all the extensions on site start with 29XX if i use this in the call forward command no call forward takes place.
