reg.x.outboundProxy.address
dotted-decimal
IP address or
hostname
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
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
The time to wait (in seconds) before failback occurs (overrides
reg.x.server.y.failOver.failBack.timeout).If the fail back 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
fail-back until a fail-over event occurs with the current server.
reg.x.outboundProxy.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.
Note that reg.x.outboundProxy.failOver.RegisterOn must be enabled.
reg.x.outboundProxy.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).
reg.x.outboundProxy.failOver.reRegisterOn
This parameters overrides reg.x.server.y.failOver.failBack.RegisterOn. 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 secondary server, since the phone will assume that the primary and secondary
servers share registration information.
The port of the SIP server to which the phone sends all requests.
