Emergency Phone 3:
Inbound Phone Book entry:
103
Outbound Phone Book entry: 203 assigned to 192.168.37.40
In this scenario, each emergency phone VOIP unit has been programmed to call one specific
extension at the head end. There is no need to assign a channel to the inbound phone book entry
because there exists only one channel for these VOIP units.
If we look at the phone book for the head end VOIP unit connected to the Attendant Phone, it should
be programmed with:
Attendant Phone:
Inbound Phone Book entries:
201 assigned to Channel 1
202 assigned to Channel 2
203 assigned to Channel 3
Outbound Phone Book entries: 101 assigned to 192.168.37.10
102 assigned to 192.168.37.20
103 assigned to 192.168.37.30
In this case, each PBX extension has been assigned a number (201, 202, and 203). Thus, when
Emergency Phone 2 places a call, it will connect to extension 202 by routing to Channel 2 on the
head end VOIP unit. The attendant also has the ability to call into each of the emergency phones by
dialing 101, 102, or 103 for the respective phones.
