Parameter
Permitted Values
Default
reg.x.server.y.useOutboundProxy
0 or 1
1
Specify whether or not to use the outbound proxy specified in reg.x.outboundProxy.address for
server x. This parameter overrides voIpProt.server.x.useOutboundProxy for registration x.
reg.x.server.y.port
0, 1 to 65535
Null
The port of the SIP server that specifies registrations. If 0, the port used depends on
reg.x.server.y.transport.
reg.x.server.y.register
0 or 1
1
If 0, calls can be routed to an outbound proxy without registration. See voIpProt.server.x.register.
For more information, see Technical Bulletin 5844: SIP Server Fallback Enhancements on Polycom Phones.
reg.x.server.y.registerRetry.baseTimeOut
10 - 120
60
The base time period to wait before a registration retry. Used in conjunction with
reg.x.server.y.registerRetry.maxTimeOut to determine how long to wait. The algorithm is defined in
RFC 5626.
reg.x.server.y.registerRetry.maxTimeOut
60 - 1800
60
The maximum time period to wait before a registration retry. Used in conjunction with
reg.x.server.y.registerRetry.baseTimeOut to determine how long to wait. The algorithm is defined in
RFC 5626.
reg.x.server.y.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.
reg.x.server.y.retryTimeOut
0 to 65535
0
The amount of time (in milliseconds) to wait between retries. If 0, use standard RFC 3261 signaling retry
behavior.
reg.x.server.y.transport
DNSnaptr,
TCPpreferred,
UDPOnly, TLS,
TCPOnly
DNSnaptr
The transport method the phone uses to communicate with the SIP server.
- Null or DNSnaptr If reg.x.server.y.address is a hostname and reg.x.server.y.port is 0 or Null,
do NAPTR then SRV lookups to try to discover the transport, ports, and servers, as per RFC 3263. If
reg.x.server.y.address is an IP address, or a port is given, then UDP is used.
- TCPpreferred TCP is the preferred transport; UDP is used if TCP fails.
- UDPOnly Only UDP will be used.
- TLS If TLS fails, transport fails. Leave port field empty (will default to 5061) or set to 5061.
- TCPOnly Only TCP will be used.
