Defaults to yes.
Enable periodic registration with the <Proxy>. This

Defaults to yes.

(dynamic) registration by the unit. If no, the dial tone will

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.
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.

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.
