Description (partial)

Using 7821, 7841, 7861 phones along with the Always Use Prime Line service parameter set to True, answering calls on lines other than Line 1 may result in the call being put on hold.

This occurs when the 78xx user does the following.

- Incoming call on Line 2
- User picks up handset and presses Line 2 immediately after (almost at the same time)
- The phone triggers an off hook event on Line 1 because of Always Use Prime Line, and then answers the incoming call on Line 2
- If the two events are close together, after answering the call on Line 2, the phone will switch back to focus on Line 1 as the active call, therefore placing the Line 2 call on hold immediately

- Always use Prime Line : True
- Handset offhook event and Line button press are close together
