If set to Null or DNSnaptr:
If voIpProt.server.x.address is
a hostname and voIp-
Prot.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 voIp-
Prot.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.

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 config-
ured overlap value.

an outbound proxy without reg-
