ASAI and Call Control
Issue 7 May 1998
4-45
1. If the hold request is for either call appearance already in the held state,
nothing else is done (request is ACKed).
2. If the hold request is for CA1 (when CA1 is in the active state), the call is
placed on soft (conference) hold.
3. If the hold request is for CA2 (when CA2 is in the active state), and CA1 is
also held, then CA2 is placed on hard-hold.
4. If the hold request is for CA2 (when CA2 is in the active state), and CA1 is
idle, the call is moved to CA1, and the call is placed on soft (conference)
hold.
When you set up repeated conferences from an analog set, you start with the call
on CA1, put it on hold (rule #2), and conference, the call ends up on CA2. The
next hold request will find the call on CA2, with CA1 idle (rule #4). Each time you
complete the conference, your call remains on CA2, so rule #4 applies repeatedly.
