Parameter
Permitted Values
Default
voIpProt.server.x.failOver.failRegistrationOn
0 or 1
0
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
0 or 1
1
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
0 or 1
0
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.
voIpProt.server.x.lcs
0 or 1
0
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
0 or 1
1
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
0 to 65535
0
The amount of time (in milliseconds) to wait between retries. If 0, use standard RFC 3261 signaling retry
behavior.
voIpProt.server.x.retryMaxCount
0 to 20
3
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
standard
Specify whether 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
0 or 1
1
Specify whether or not to use the outbound proxy specified in voIpProt.SIP.outboundProxy.address for
server x.
voIpProt.server.H323.x.address
dotted-decimal IP
address or
hostname
Null
Address of the H.323 gatekeeper. Note: Only one H.323 gatekeeper per phone is supported; if more than one is
configured, only the first is used.
