Default Interpretation
Null IP address or host name and
port of a SIP server that accepts
registrations. Multiple servers
can be listed starting with x=1,
Null
2, ... for fault tolerance.
If port is 0 or Null:
If voIpProt.server.x.address is a
hostname and voIp-
Prot.server.x.transport is set to
DNSnaptr, do NAPTR then
SRV lookups.
If voIpProt.server.x.transport is
set to TCPpreferred or
UDPonly then use 5060 and
don't advertise the port number
in signalling.
If voIpProt.server.x.address is
an IP address, there is no DNS
lookup and 5060 is used for the
port but it is not advertised in
signaling.
If port is 1 to 65535:
This value is used and it is
advertised in signaling.
DNSna If set to Null or DNSnaptr:
ptr 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.
