Dialing from Other PBX Line or from PSTN
To configure the call, follow these steps:
1
Dial the PBX subscriber number the same way as if the user's phone was connected
directly to PBX.
2
Immediately as PBX rings into 8FXO, the ring signal is "send" to phone connected to
8FXS.
3 Once the phone's handset, connected to 8FXS is raised, the 8FXO seizes the PBX line
and the voice path is established between the phone and the PBX line.
4 There is a one to one mapping between PBX lines and 8FXS ports. Each PBX line is
routed to the same phone (connected to 8FXS).
5
The call is disconnected when phone connected to 8FXS goes onhook.
