Toggling during the three-party phase
If Z toggles (Norstar sends a recall signal) while calls with both X and Y are
established, the active party is put on hold, and the held party becomes
active. If the active call is not established (for example, dialing, ringing,
or busy), it is disconnected.
If the held party has released, then if the active call is established it is put on
hold, otherwise it is disconnected; in both cases dialtone is provided to Z.
Active or held party disconnects during the three-party phase
If the active party (X or Y) disconnects during the three-party phase,
dialtone is provided to Z and a new call can be processed. If the party on
hold (X or Y) disconnects, the active call is unaffected. In both cases, the
AC15 trunk is not disconnected.
Complete the transfer
Party Z completes the transfer from X to Y, regardless of which is the active
party, by going on-hook (Norstar sends a release signal). The transfer is
allowed when the active call is ringing or established. Note that if Y is a
trunk, although Z is hearing ringback tone, the call will not be considered in
a proper state for being transferred until Y’s end of dialing timer (EOD or
ODT) has expired, or Z has pressed the # sign. In the other call states,
the active call is abandoned and the held party recalls the attendant. If
the call cannot be transferred due to access restrictions, the active party
is disconnected and the held party is given the Access Denied (ACCD)
intercept treatment. In all cases, when the release signal is received, the
AC15 trunk is disconnected.
