Description
Enables periodic registration with the proxy. This
parameter is ignored if a proxy is not specified. To
enable this feature, select Yes.
Default: Yes
Enables making outbound calls without successful
(dynamic) registration by the phone. If set to No, the
dial tone plays only when registration is successful.
To enable this feature, select Yes.
Default: No
Defines how often the phone renews registration with
the proxy. If the proxy responds to a REGISTER with
a lower expires value, the phone renews registration
based on that lower value instead of the configured
value.
If registration fails with an "Expires too brief" error
response, the phone retries with the value specified
in the Min-Expires header of the error.
The range is from 32 to 2000000.
Default: 3600 seconds
If enabled, the user does not have to be registered with
the proxy to answer calls.
Default: No
Enables DNS SRV lookup for the proxy and outbound
proxy. To enable this feature, select Yes. Otherwise,
select No.
Default: No
Enables the phone to automatically prepend the proxy
or outbound proxy name with _sip._udp when
performing a DNS SRV lookup on that name.
Default: No
Sets the delay after which the phone retries from the
highest priority proxy (or outbound proxy) after it has
failed over to a lower priority server.
The phone should have the primary and backup proxy
server list from a DNS SRV record lookup on the
server name. It needs to know the proxy priority;
otherwise, it does not retry.
The range is from 0 to 65535.
Default: 3600 seconds
