Figure 3 – 1 Line PA + 1 Line WIP + PIB VoIP Proxy
Figure 4 shows an expansion to Figure 3 so that BGM (music) audio and / or paging
console audio can be sent to or received from other QE20s.
A second VIF and ATA is added to each QE20, and the PIB configured for additional
channels of VoIP Proxy functions. Each VIF + ATA pair provides two channels of
audio that can be sent or received over the network.
The QE20 panel is configured with Script commands to control VIF #1 (and so the
ATA #2) so that calls can be made or received.
