Configuration using S2 IP Address
Points to remember
When an IP set registers to the main office using S2, remember the
following important points:
•An IP Phone registered to the main office using S2 appears in the main
office TPS as a "regular online" user. Normally, an MG 1000B IP Phone
registered to the main office Call Server appears as a "branch online"
user. Commands can be executed on the main office Signaling Server
to verify this operation.
•The display on an IP Phone registered to the main office using S2 does
not show the "Branch USER: XXXX" prompt.
•For an MG 1000B IP Phone to register successfully with the mainoffice
TPS using S2, relaxed node ID checking must be used. Four digits must
be configured for the Node IP Address on both the main office TPS
and MG 1000B TPS. The first three digits must be the same, and are
configured as the Node ID on the IP Phones.
•When an MG 1000B IP Phone is registered to the main office using S2,
an administrator must manually redirect the IP Phone back to the MG
1000B TPS once the IP Phone becomes available again. This action
enables the MG 1000B IP Phone to go back to Normal Mode by using
S1 to register to the main office.
•If the MG 1000B TSP or MGC becomes unavailable, MG 1000B
IP Phones registered to the main office TPS (in Normal Mode) are
unaffected. MG 1000B IP Phones that are rebooted try to register using
S1, or S2 if programmed.
•The main office can be either a CS 1000M Large System or a CS
1000E. If the main office is any system other than a CS 1000M Large
