Chapter 14 Third Party Call Control Service
14.1 Overview
14.1.1 Introduction to Third Party Call Control Service
A third party, usually an authorized administrator can preset a call task on the XE IP
PBX. The XE IP PBX then will invite the call participants (A and B) to join the call at the
preset time and to have a conversation. Two participants, namely, parties A and B, are
supported by the third party call control service.
To use the third party call control service, the MS should be enabled on the XE IP PBX
first.
14.1.2 Working Process of Third Party Call Control Service
The third party call control service works as follows:
1) An authorized administrator logs on to the XE IP PBX and predefines a call task as
described in Third Party Call Control Service Configuration .
2) The phone of call participant A rings at the preset time.
3) Party A picks up the phone and then the phone of call participant B rings.
4) Party B picks up the phone and the conversation between party A and party B
begins. The corresponding call task is deleted from the XE IP PBX at the same
time.
5) Both parties hang up the phone when the conversation ends.
Note:
If A does not pick up the receiver in time, A will stop ringing after the time expires on the
server and the XE IP PBX will end and delete the call. On the other hand, if A has
picked up the phone, but B has not in time, the XE IP PBX will end and delete the call as
well.
