Configuring non-zero S2 IP Addresses

System or a CS 1000E, a TN mismatch occurs and redirection from
Branch Office to main office is not successful.

If the MG 1000B TPS is unavailable, IP Phones at the main office or
Branch Office have no access to TDM resources (digital and analog
telephones or PSTN trunks) at the Branch Office, whether the IP Phones
are registered using S1 or S2.

Bandwidth management zones, emergency access, and time of day
continue to work normally, regardless of whether an IP Phone is
registered using S1 or S2.

If the MGC and CP PM at the Branch Office are initialized or rebooted
simultaneously, MG 1000B IP Phones can register using S1 or S2. In
this case, an administrator must manually redirect the S2-registered IP
Phones to register using S1 again.

If the main office contains a survivable remote gateway, then MG 1000B
IP Phones can register successfully using either S1 or S2 when the
main office Call Server becomes unavailable.

MG 1000B IP Phones registered to the main office using S2 are not
redirected to the MG 1000B TPS during IP Phone firmware upgrade
at the main office. MG 1000B IP Phones registered using S2 receive
firmware upgrades in the same manner as main office IP Phones. The
first time the MG 1000B IP Phone reboots after the firmware upgrade,
it is directed to the MG 1000B TPS using S1. Any different firmware is
applied at that time, before the IP Phone is redirected back to the main
office TPS.

MG 1000B IP Phones registered using S1 are redirected back to the
MG 1000B Signaling Server for any firmware upgrades, as described in

"Firmware downloads" (page 345)

.

MG 1000B IP Phones registered using S2 do not display "Test Local
Mode."
