SYNTAX Unsigned32 (0..600)
MAX-ACCESS read-write
STATUS current
DESCRIPTION
"In SIP, a registration is valid for a period of time decided by the registrar.
Once a unit is registered, the SIP protocol requires the User Agent to refresh
this registration before the registration expires. Typically, this
re-registration must be completed before the ongoing registration expires, so
that the User Agent's registration state will not change (i.e. will remain
'registered').
This variable defines the time, relative to the end of the registration, at
which a registered unit will begin updating its registration.
For example, if the registration lasts 60 minutes, and sipReRegistrationTime is
set to 43, the unit will send new REGISTER requests 59 minutes and 17 seconds
after the reception of the registration acknowledgement (43 seconds before the
end of the registration period).
Setting sipReRegistrationTime to 0 will have for effect that the User Agent will
fall into the 'unregistered' state BEFORE sending the re-REGISTER requests.
This value is expressed in seconds(s) and MUST be lower than the value of the
Expires header of the contact in the 200 OK response to the REGISTER, otherwise
the unit rapidly sends REGISTER requests continuously."
