Description

SIP proxy server and port number set by the Service Provider for all outbound requests.
For example: 192.168.2.100:6060.

Outbound Proxy
SIP Outbound Proxy Server where all outbound requests are sent as the first hop.

if
Defaults to yes.
Register
Enable periodic registration with the
specified.
Defaults to yes.
Make Call Without Reg
Allow making outbound calls without successful (dynamic) registration by the unit. If no,
the dial tone will not play unless registration is successful.
Defaults to no.
Register Expires
Allow answering inbound calls without successful (dynamic) registration by the unit. If proxy
responded to REGISTER with a smaller Expires value, the phone will renew registration based
on this smaller value instead of the configured value. If registration failed with an Expires too
brief error response, the phone will retry with the value given in the Min-Expires header in the
error response.
Defaults to 60.
Ans Call Without Reg
If enabled, the user does not have to be registered with the proxy to answer calls.
Defaults to no.
Use DNS SRV
Whether to use DNS SRV lookup for Proxy and Outbound Proxy.
Defaults to no.
DNS SRV Auto Prefix
If enabled, the phone will automatically prepend the Proxy or Outbound Proxy name with
_sip._udp when performing a DNS SRV lookup on that name.
Defaults to no.
Proxy Fallback Intvl
This parameter sets the delay (sec) after which the phone will retry from the highest
priority proxy (or outbound proxy) servers after it has failed over to a lower priority
server. This parameter is useful only if the primary and backup proxy server list is
provided to the phone via DNS SRV record lookup on the server name. (Using multiple
DNS A record per server name does not allow the notion of priority and so all hosts will
be considered at the same priority and the phone will not attempt to fall back after a fail
over).
Defaults to 3600
