If set to Null or DNSnaptr:
If
voIpProt.server.x.address
is a
hostname and voIpProt.server.x.port is 0 or
Null, do NAPTR then SRV look-ups to try to
discover the transport, ports and servers, as
per RFC 3263. If
voIpProt.server.x.address
is an IP
address, or a port is given, then UDP is used.
If set to TCPpreferred:
TCP is the preferred transport, UDP is used if
TCP fails.
If set to UDPOnly:
Only UDP will be used.
If set to TLS:
If TLS fails, transport fails. Leave port field
empty (will default to 5061) or set to 5061.
If set to TCPOnly:
Only TCP will be used.
NOTE: TLS is not supported on SoundPoint
IP 300 and 500 phones.
voIpProt.server.x.expires positive
integer,
minimum
300
3600 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”=3600 and
“overlap”=60, the phone will re-register after
3540 seconds (3600 – 60).
voIpProt.server.x.expires.overlap positive
integer,
minimum 5,
maximum
65535
60 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 that value is less than the
configured overlap value.
voIpProt.server.x.register 0, 1 1 If set to 0, calls can be routed to an outbound
proxy without registration.
voIpProt.server.x.retryTimeOut Null or
non-negativ
e integer
0 If set to 0 or Null, use standard RFC 3261
signaling retry behavior. Otherwise
retryTimeOut determines how often retries
will be sent.
Units = milliSeconds. (Finest resolution =
100ms).
