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. GVC3210 supports both synchronized and non-synchronized MWI.
The default setting is "No".
This option is used to enable or disable session timer on the GVC3210 side when
server side can provide both session timer UPDATE or session audit UPDATE.
The default setting is "Yes".
It is used to configure the device's SIP session timer period (in seconds). 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 with a valid range
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 OPTIONS 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".
