Parameter
Permitted Values
Default
voIpProt.SIP.ms-forking
0 or 1
0
If set to 0, support for MS-forking is disabled. If set to 1, support for MS-forking is enabled and the phone rejects
all Instant Message INVITEs. This parameter applies when installing Microsoft Live Communications Server.
Note that if any end point registered to the same account has MS-forking disabled, all other end points default
back to non-forking mode. Windows Messenger does not use MS-forking so be aware of this behavior if one of
the end points is using Windows Messenger.
voIpProt.SIP.mtls.enable
0 or 1
1
If 0, Mutual TLS is disabled. If 1, Mutual TLS is enabled. Used in conjunction with Microsoft Lync 2010.
voIpProt.SIP.musicOnHold.uri
a SIP URI
Null
A URI that provides the media stream to play for the remote party on hold. This parameter is used if
reg.x.musicOnHold.uri is Null. Note: The SIP URI parameter transport is supported when configured with
the values of UDP, TCP, or TLS.
voIpProt.SIP.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.
voIpProt.SIP.outboundProxy.port
0 to 65535
0
The port of the SIP server to which the phone sends all requests.
voIpProt.SIP.outboundProxy.failOver.failBack.mode
newRequests,
DNSTTL,
registration,
duration,
newRequests
The mode for failover failback (overrides voIpProt.server.x.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.
voIpProt.SIP.outboundProxy.failOver.failBack.timeout
0, 60 to 65535
3600
The time to wait (in seconds) before failback occurs (overrides
voIpProt.server.x.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 does not failback until a failover event occurs with the current server.
voIpProt.SIP.outboundProxy.failOver.failRegistrationOn
0 or 1
0
When set to 1, and the reRegisterOn parameter is enabled, the phone silently invalidates an existing
registration (if it exists), at the point of failing over. When set to 0, and the reRegisterOn parameter is enabled,
existing registrations remains active. This means that the phone attempts a failback without first attempting to
register with the primary server to determine if it has recovered.
Note that voIpProt.SIP.outboundProxy.failOver.RegisterOn must be enabled.
