Administrator Guide - SoundPoint
the case of static server lists, when a server registration fails, registration will be
attempted on another server. If the phone is not registered to the first server in the list
when registration fails, it will start by trying to register to the first server. When mak-
ing a new call, if the INVITE fails, the other servers in the list will be tried one by one
for routing signaling until the last server is tried.
Definition of signaling failure (registration or start of call):
• If TCP is used: The signaling fails if the connection fails or the Send fails.
• If UDP is used: The signaling fails if ICMP is detected or if the signal times

3.6.5.1 DNS SIP Server Name Resolution

If a DNS name is given for a proxy/registrar address, the IP address(es) associated
with that name will be discovered as specified in RFC 3263 - Locating SIP Servers. If
a port is given, the only lookup will be an A record. If no port is given, NAPTR and
SRV records will be tried, before falling back on A records if NAPTR and SRV
records return no results. If no port is given, and none is found through DNS, 5060
will be used.
See http://www.ietf.org/rfc/rfc3263.txt for an example.

last server then the signaling fails after the complete UDP timeout defined in
RFC 3261. If it is not the last server in the list, the maximum number of retries
using the configurable retry timeout is used. For more information, see
