Description
This parameter adjusts the time delay before calls are forwarded. The
default value is 20.
For example, delayed call forwarding specifies the time before a
call is sent to a forwarded number or sent to the voice mailbox.
If the parameter is set to Yes, the call transfer, call forwarding and
Do-Not-Disturb (DND) functions are supported locally.
There are three options, and the default value is Log All Calls.
 Log All Calls: record all calls.
 Log Incoming/Outgoing only: The missed call records are not
displayed.
 Disable Call Log: disable call records.
Session Expiration is the time (in seconds) that is considered as the
duration for timeout, when no successful session refresh transaction
occurs beforehand. The default value is 180.
The SIP Session Timer extension enables SIP sessions to be
periodically refreshed through a SIP request (UpDATE or
re-INVITE). Once the session interval expires and there is no refresh
through the UpDATE or re-INVITE message, the session is
terminated.
This parameter defines the minimum session expiration (in seconds).
The default value is 90.
If the parameter is set to Yes, the phone uses the Session Timer when
an outgoing call is made and the remote party supports the Session
Timer.
If the parameter is set to Yes, the phone uses the Session Timer when
an incoming call is received with Session Timer requests.
If the parameter is set to Yes, the phone uses the Session Timer even
if the remote party does not support this feature. If the parameter is
set to No, the Session Timer is enabled only when the remote party
supports this feature. To disable the Session Timer, select No for
Caller Request Timer, Callee Request Timer, and Force Timer.
As a calling party, select UAC to use the phone as the refresher, or
UAS to use the called party or proxy server as the refresher.
As a called party, select UAC to use calling party or proxy server as
the refresher, or UAS to use the phone as the refresher.
Session Timer can be refreshed in the INVITE or UpDATE method.
Select Yes to adopt the INVITE method to refresh the Session Timer.
The PRACK method enables reliability to SIP provisional responses
(1xx series). This is necessary for supporting the PSTN network.
There are four different ring tones:
One system ring tone: When this option is selected, all calls will ring
with the system ring tone.
