Description
This is the maximum wait time between attempts to
reregister. Once this maximum is reached, Coral
SeaBeam will wait this time for all subsequent
attempts.
For example, if the minimum time is 20 seconds and
the maximum time is 120 seconds, Coral SeaBeam
will attempt to reregister as follows:
Wait 20 secs
Attempt to connect
If fail, wait 40 secs
Attempt to connect
If fail, wait 80 secs
Attempt to connect
If fail, wait 120 secs (the maximum)
Attempt to connect
If fail, wait 120 secs, and so on
The factory setting is 1800 seconds.
Typically On, to instruct Coral SeaBeam to send SIP
keep-alive messages in order to maintain a "pinhole"
through your firewall for SIP messaging.
Typically On.
A session timer is a mechanism to detect whether a
call session is still active from the signaling point of
view. When the timer expires, a refresh is sent from
one party to the other. The timer is then reset.
Turn On to enable session timer. Enter a value in
the Default session time field. The factory setting
is 60 seconds.
Turn Off to disable session timer; refreshes will
never be sent.
This field specifies your preference for which party
should send the refresh. The preference is not a
guarantee that the refresh will be performed by the
specified party. The options are:
None - No preference
Local refreshes - Your computer sends
Remote refreshes - The other party sends
UAC refreshes - The user agent client (the party
that initiated communication) sends
UAS refreshes - The user agent server (the other
party) sends
