With Shared Voice Connections, two voice calls can share a single trunk connection between the cell phone and the PBX. For example, if the user is talking to someone and they need to put the call on hold, using the cell phone second call appearance the user dials the Hold FNE (or uses the FMC application). The first call looks to be dropped at the cell phone, but is really on hold in Communication Manager. When you initiate or answer a 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 access and connect the held call using Recall FNE. You can use shared voice connection option only with the FMC applications such as PBFMC, PVFMC, and SPFMC.
