When the busy station returns to idle, you receive a Callback.
1. Answer the callback in the normal manner.
2. Await answer from the previously called station.
Note:
A maximum of 5 simultaneous callbacks can be active. Call backs are returned in the
order received at the Station (your callback may not be first in line). If you do not answer
a callback ring within 15 seconds, the callback is cancelled.
5.3 Leaving a Return Call Message
When a station user does not answer your call or is in DND, you may request the user
callback when available. The station receives a Message Wait indication and responds
using the procedure in Responding to a Message Wait section discussed later in this guide.

5.4 Camping-on to a Busy Station

party of your call waiting. When camped-on, the system sends a call wait tone to the busy

ignore your call, or enter DND.

the two stations is synchronized; when one is busy the other is busy and when one is in DND
the other is in DND. Either can activate and deactivate user features.
