Enable 100rel
The use of the PRACK (Provisional Acknowledgment) method enables reliability
to SIP provisional responses (1xx series). This is very important in order to
support PSTN internetworking. To invoke a reliable provisional response, the
100rel tag is appended to the value of the required header of the initial signaling
messages.
Caller ID Display
When set to “Auto”, the phone will look for the caller ID in the order of P-Asserted
Identity Header, Remote-Party-ID Header and From Header in the incoming SIP
INVITE. When set to “Disabled”, all incoming calls are displayed with
“Unavailable”. When set to “From Header”, the phone will display the caller ID
based on the From Header in the incoming SIP INVITE.
Default setting is “Auto”.
Ignore Alert-Info
Header
This option is used to configure default ringtone. If set to “Yes”, configured
default ringtone will be played even if Alert-info header is present.
