QSIG Port Setting [Monitored PBX]
ISDN-QSIG (PBX Direct Connection)
Each QSIG port of a BRI or PRI card that will be used to transmit extension status information must be
set to do so through system programming. Even if a port is set to not transmit information, it will still
receive information from other PBXs.

IP-GW-QSIG
IP data is routed through the network according to the routing tables of the IP-GW cards. When using
VoIP, it is necessary to identify the monitor PBXs, to which to transmit extension status information, for
each card that will be used. This is done by specifying the extension number of any extension (for
example, the PBX operator) at the monitor PBX as a Network Operator extension for that IP-GW card.
