Required settings
This parameter must be
configured to provide redundant
sip servers FQDN for the phone
to connect to.
It must contain only 1 entry of the
following format.
host1[:port1]
[;transport1=xxx];
Host must be a FQDN. Host
cannot be IPV6 address.
Port and transport values are
optional. However, if these values
are known, provide them in the
settings.
An example setting:
SIP_CONTROLLER_LIST =
servers.sample.com:tcp:
5060
environment
SIP server redundancy
Note:
When
SIP_CONTROLLER_LIST
contains FQDN, phone uses
DNS to resolve the FQDN
into IP addresses. If an
FQDN resolves to multiple IP
addresses, phone uses the
first two resolved entries. If
the FQDN resolves to one
entry or if the host in
SIP_CONTROLLER_LIST
contains an IPV4 address,
though supported, it is not a
redundant signaling
configuration.
