9.f PBX to PBX connectivity – using FXS only

Out-dialled calls from the PBX can pass a dialled number to the Vega; it can use this to decide which destination VoIP gateway to route the call to (i.e. multiple destination gateways may be supported).

Considerations

•Call transfer from a PBX extension to the other PBX may not be blocked by the PBX if the local PBX does not allow call transfers to Trunk Interfaces

•Calls presented FXS to PBX can only provide ringing voltage to indicate call arrival. Just as PSTN calls to analog trunk interfaces of a PBX have to be routed to an operator or auto attendant, so do calls from the Vega FXS.

9.g PBX to PBX connectivity – using FXO only

To connect to the far end PBX, call the local PBX extension number of a line connected to the FXO gateway. Calling this local extension number will trigger the local FXO gateway to immediately set up a VoIP call to the far end FXO gateway. The caller will receive dial tone from the far end PBX – the caller can then dial the desired destination number into the far end PBX.

Considerations

•Need disconnect supervision on at least 1 Vega – preferably both.
