I recently deleted (by accident!) the very first phone on my hunt group of 4. The problem now is that after re-installing the phone (identically as far as I can tell) the incoming call will not 'hunt' to the next available phone in the group, just say that 'the extension you have dialled is busy, please try again later.' I have tried understanding the 8000 page manual, but to no avail! Does the first phone require to be set up as a 'pilot' DN & if so, how is this done. Any help would be greatly appreciated...
