It is used to configure the time period (in minutes) in which the device refreshes its
registration with the specified registrar. The default setting is 60. The maximum
value is 64800 (about 45 days) and the minimum value is 1 minute.
It is used to configure the time period (in seconds) in which the device will retry the
registration process in the event that is failed. The default setting is 20. The
maximum value is 3600 (1 hour).
It is used to configure the local SIP port used to listen and transmit. The default
setting is 5060. The valid range is from 5 to 65535.
It is used to set if the device will subscribe voice message service. If it is set to "Yes",
the device will periodically send SIP SUBSCRIBE message for Message Waiting
Indication service. GVC3200/GVC3202 supports both synchronized and non-
synchronized MWI. The default setting is "No".
It is used to set if the device will use the session timer. If it is set to "Yes", it will be
added in the SIP INVITE message to notify the server. The default setting is "Yes".
It is used to configure the device'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.
It is used to configure the minimum session expiration timer (in seconds) if the
device acts as a timer refresher. The default setting is 90. The valid range is from 90
to 64800.
It is used to set the party which will refresh the active session if the device makes
outbound calls. If it is set to "UAC" and the remote party does not support Refresher
feature, the device 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".
It is used to set the party which will refresh the active session if the device 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 device
will refresh it. The default setting is "UAC".
It is used to set the SIP message type to refresh the session. If it is set to "Yes", the
Session Timer will be refreshed by using the SIP INVITE message. Otherwise, the
device will use the SIP UPDATE or SIP OPTION message. The default setting is
"No".
This is used to set the caller party to act as refresher. If set to "Yes" and both parties
support session timers, the device will enable the session timer feature when it
makes outbound calls. The SIP INVITE will include the content "refresher=uac". The
default setting is "No".
