This is an odd one.
The customer has 8 lines. They are not interested in parking calls, they simply wanted to be able to put a call on hold, then page "so and so, you have a call on line 3,) then the person could press the appropriate line key and pick up the call.
What is happening, right now is if the receptionist puts a call on hold, other callers can pick it up by pressing the appropriate line key. However, if anyone else puts a call on hold, when someone else tries to pick it up via the trunk key, they get "Main Lines Busy" (Main Lines is the name of the CO Trunk Group).
I have gone into the appropriate trunk groups and added the list for all extension to Answer Access. If there is something else I am missing, please let me know.
