In the Shared Voice Connections feature, you can share a single trunk for multiple calls as follows:
The user makes a call that is connected to the Communication Manager and they make another very short call (dialing an FNE) to put that call on hold. The connection between the cell phone and the Communication Manager is still active and can be used to dial another call. In this way one connection between the cell phone and the Communication Manager is used to manage two phone calls.
Any time you initiate or answer the second cell phone call, the first call is put on hold at the PBX and its voice connection is dropped; it is combined with the new active call as a shared connection. You can use shared voice connection option only with the FMC applications such as PBFMC, PVFMC, and SPFMC.
You can use the Recall FNE, Conference Complete FNE, and Transfer Complete FNE with the shared voice connection feature as follows:
When you have a shared connection having an active voice call and a held call you can dial the Recall FNE to put the active call on hold and connect to the previously held call.
You can use the Conference Complete FNE or the Transfer Complete FNE when there is an active call and a held call in a shared connection. The Conference Complete FNE conferences the two voice calls together while the Transfer Complete FNE transfers the held call to the active voice call.
Note:
If the long hold recall timer is administered, then you do not need to use the Recall FNE. The held call will be connected as soon as the long hold recall timer is expired and the active call will be placed on hold at office telephone.
With the PVFMC application you need not use the Shared Voice Connection feature since SIP supports signaling hold, transfer, and conference.
When your OPTIM application is part of one shared voice connection, you cannot be part of any other shared voice connection. You can use the same call appearance in multiple shared voice connection when the connections are associated with different OPTIM applications.
When you establish a shared connection, additional calls initiated or answered by the cell phone do not have any effect on the existing calls. When the active voice calls drops and only held call is there, then the shared connection becomes a residual shared connection. When the cell phone initiates or answers a new call, then the new call is added to the residual shared connection to form a shared connection. You can use the Held Appearance Select FNE to connect to the held call in a residual shared connection.
