Use OB Proxy In Dialog SIP requests are sent to the outbound proxy within
a dialog. This field is ignored if Use Outbound
Proxy is set to no, or Outbound Proxy is blank. To
enable this feature, select yes. Otherwise, select
no. Defaults to yes.
Register Enables periodic registration with the proxy. This
parameter is ignored if a proxy is not specified. To
enable this feature, select yes. Otherwise, select
no. Defaults to yes.
Make Call Without Reg 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. Otherwise, select
no. Defaults to no.
Register Expires 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 0 to 268435455. Defaults to 3600
seconds.
Ans Call Without Reg The user does not have to be registered with the
proxy to answer calls. To enable this feature, select
yes. Otherwise, select no. Defaults to no.
Use DNS SRV Enables DNS SRV lookup for the proxy and
outbound proxy. To enable this feature, select yes.
Otherwise, select no. Defaults to no.
DNS SRV Auto Prefix The phone automatically prepends the proxy or
outbound proxy name with _sip._udp when
performing a DNS SRV lookup on that name. To
enable this feature, select yes. Otherwise, select
no. Defaults to no.
