message for Message Waiting Indication service. GXV3240 phone system
supports both synchronized and non-synchronized MWI. Default is "No".
Enables SIP OPTIONS to track account registration status so the phone
will send periodic OPTIONS message to server to track the connection
status with the server. The default setting is "No".
Configures the time interval when the phone sends OPTIONS message to
SIP server. The default setting is 30 seconds, which means the phone will
send an OPTIONS message to the server every 30 seconds. The default
range is 1-64800.
Configures the maximum times of sending OPTIONS message
consistently from the phone to server. Phone will keep sending OPTIONS
messages until it receives response from SIP server. The default setting is
"3", which means when the phone sends OPTIONS message for 3 times,
and SIP server does not respond this message, the phone will send RE-
REGISTER message to register again. The valid range is 3-10.
Allows the phone system to use the session timer, when set to "Yes", it will
be added in the SIP INVITE message to notify the server.
Default setting is "Yes"
Configures the phone system's SIP session timer. It enables SIP sessions
to be periodically "refreshed" via a SIP request (UPDATE, or re-INVITE). If
there is no refresh via an UPDATE or re-INVITE message, the session will
be terminated once the session interval expires. Session Expiration is the
time (in seconds) where the session is considered timed out, provided no
successful session refresh transaction occurs beforehand.
The default setting is 180. The valid range is from 90 to 64800.
Determines the minimum session expiration timer (in seconds) if the phone
act as a timer refresher. The default setting is 90. The valid range is from
90 to 64800.
Sets which party will refresh the active session if the phone makes
outbound calls. If it is set to "UAC" and the remote party does not support
Refresher feature, the phone system will refresh the active session. If it is
set to "UAS", the remote party will refresh it. If it is set to "Omit", the header
will be omitted so that it can be selected by the negotiation mechanism.
The default setting is "Omit".
Specifies which party will refresh the active session if the phone receives
inbound calls. If it is set to "UAC", the remote party will refresh the active
session. If it is set to "UAS" and the remote party does not support refresh
feature, the phone system will refresh it. The default setting is "UAC".
Sets the SIP message type for refresh the session. If it is set to "Yes", the
Session Timer will be refreshed by using the SIP INVITE message.
