You can list multiple registration servers for fault tolerance. In the table
you can list four servers by using y=1 to 4. If the reg.x.server.y.address is not null, all of the
parameters in the following table will override the parameters specified in voIpProt.server.*
server registration parameters are listed in the following table:
Registration Server Parameters
Parameter
reg.x.server.H323.y.expires
Desired registration period.
reg.x.server.y.address
The IP address or host name of a SIP server that accepts registrations. If not Null, all of the parameters in this
table will override the parameters specified in voIpProt.server.*. Notes: If this parameter is set, it will take
precedence even if the DHCP server is available.
reg.x.server.y.expires
The phone's requested registration period in seconds. Note: The period negotiated with the server may be
different. The phone will attempt to re-register at the beginning of the overlap period. For example, if
expires="300" and overlap="5", the phone will re-register after 295 seconds (300–5).
reg.x.server.y.expires.lineSeize
Requested line-seize subscription period.
reg.x.server.y.expires.overlap
The number of seconds before the expiration time returned by server x at which the phone should try to re-
register. The phone will try to re-register at half the expiration time returned by the server if the server value is
less than the configured overlap value.
