voIpProt.server.x.failOver.failRegistrationOn
When set to 1, and the reRegisterOn parameter is enabled, the phone will silently invalidate an
existing registration (if it exists), at the point of failing over. When set to 0, and the reRegisterOn
parameter is enabled, existing registrations will remain active. This means that the phone will attempt
failback without first attempting to register with the primary server to determine if it has recovered.
voIpProt.server.x.failOver.onlySignalWithRegistered
When set to 1, and the reRegisterOn and failRegistrationOn parameters are enabled, no signaling is
accepted from or sent to a server that has failed until failback is attempted or failover occurs. If the
phone attempts to send signaling associated with an existing call via an unregistered server (for
example, to resume or hold a call), the call will end. No SIP messages will be sent to the unregistered
server. When set to 0, and the reRegisterOn and failRegistrationOn parameters are enabled, signaling
will be accepted from and sent to a server that has failed (even though failback hasn’t been attempted
or failover hasn’t occurred).
voIpProt.server.x.failOver.reRegisterOn
When set to 1, the phone will attempt to register with (or via, for the outbound proxy scenario), the secondary
server. If the registration succeeds (a 200 OK response with valid expires), signaling will proceed with the
secondary server. When set to 0, the phone won’t attempt to register with the second.
If 0, the Microsoft Live Communications Server (LSC) is not supported. If 1, LCS is supported for registration x.
This parameter overrides voIpProt.SIP.lcs .
voIpProt.server.x.register
If 0, calls can be routed to an outbound proxy without registration. See reg.x.server.y.register.
For more information, see Technical Bulletin 5844: SIP Server Fallback Enhancements on Polycom Phones.
voIpProt.server.x.retryTimeOut
The amount of time (in milliseconds) to wait between retries. If 0, use standard RFC 3261 signaling retry behavior.
voIpProt.server.x.retryMaxCount
If set to 0, 3 is used. The number of retries that will be attempted before moving to the next available server.
voIpProt.server.x.specialInterop
standard,
ocs2007r2, lcs2005,
lync2010
Specify if this registration should support Microsoft Office Communications Server 2007 R2 (ocs2007r2), Microsoft
Live Communications Server 2005 (lcs2005), or Microsoft Lync 2010 (lync2010).
voIpProt.server.x.useOutboundProxy
Specify whether or not to use the outbound proxy specified in voIpProt.SIP.outboundProxy.address for
server x.
