The Multi-party Call Control service enhances the functionality of the Generic Call Control Service with leg
management. It also allows for multi-party calls to be established, i.e. up to a service specific number of legs can be connected simultaneously to the same call.
The Multi-party Call Control Service is represented by the IpMultiPartyCallControlManager
interfaces that interface to services provided by the network. Some methods are asynchronous, in that they do not lock a thread into waiting whilst a transaction performs.
In this way, the client machine can handle many more calls, than one that uses synchronous message calls. To handle responses and reports, the developer must implement IpAppMultiPartyCallControlManager
to provide the callback mechanism.
