Description
SIP proxy server and port number set by the Service Provider for all outbound requests. For example: 192.168.2.100:6060.
Enable the use of <Outbound Proxy>. If set to no, <Outbound Proxy> and <Use OB Proxy in Dialog) is ignored. Defaults to no.
SIP Outbound Proxy Server where all outbound requests are sent as the first hop.
Whether to force SIP requests to be sent to the outbound proxy within a dialog. Ignored if <Use Outbound Proxy> is no or <Outbound Proxy> is empty.
Defaults to yes.
Enable periodic registration with the <Proxy>. This parameter is ignored if <Proxy> is not specified.
Defaults to yes.
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.
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
Defaults to 60.
If enabled, the user does not have to be registered with the proxy to answer calls. Defaults to no.
Whether to use DNS SRV lookup for Proxy and Outbound Proxy.
Defaults to no.
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.
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
