Parameter
Permitted Values
Default
reg.x.lisdisclaimer
string, 0 to 256
characters
Null
Sets the value of the location policy disclaimer. For example, the disclaimer may be “Warning: If you do not provide
a location, emergency services may be delayed in reaching your location should you need to call for help.” This
parameter is set by in-band provisioning when the phone is registered to Microsoft Lync Server 2010.
reg.x.lync.autoProvisionCertLocation
0 to 6
6
If 0, the certificate download is disabled. If non-0, the certificate corresponding to the index of the appropriate
sec.TLS.customCaCert.X is downloaded.
reg.x.musicOnHold.uri
a SIP URI
Null
A URI that provides the media stream to play for the remote party on hold. If present and not Null, this parameter
overrides voIpProt.SIP.musicOnHold.uri.
reg.x.outboundProxy.address
dotted-decimal
IP address or
hostname
Null
The IP address or hostname of the SIP server to which the phone sends all requests.
reg.x.outboundProxy.failOver.failBack.mode
newRequests
DNSTTL
registration
duration
newRequests
The mode for failover failback (overrides reg.x.server.y.failOver.failBack.mode).
- newRequests All new requests are forwarded first to the primary server regardless of the last used server.
- DNSTTL The phone tries the primary server again after a timeout equal to the DNS TTL configured for the server
that the phone is registered to.
- registration The phone tries the primary server again when the registration renewal signaling begins.
- duration The phone tries the primary server again after the time specified by
reg.x.outboundProxy.failOver.failBack.timeout expires.
reg.x.outboundProxy.failOver.failBack.timeout
0, 60 to 65535
3600
The time to wait (in seconds) before failback occurs (overrides
reg.x.server.y.failOver.failBack.timeout). If the failback mode is set to Duration, the phone waits this
long after connecting to the current working server before selecting the primary server again. If 0, the phone will not
failback until a failover event occurs with the current server.
reg.x.outboundProxy.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. Note that
reg.x.outboundProxy.failOver.RegisterOn must be enabled.
reg.x.outboundProxy.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).
