Non Invite Retry
Times
The maximum number of times that a SIP
message other than an INVITE request is
retransmitted if no response is received.
According to RFC3261, Non-INVITE requests
are retransmitted at an interval which starts
at T1 and doubles until it hits T2, and then
repeats at interval T2. The MTA stops
retries when a 32 second cap is reached, or
the max number of non-INVITE retries has
been attempted.
Register Expiration
Time
Time to wait after a registration before it
expires.
Generic SIP version: If the timer is set to
be x seconds, the MTA re-registers at
$ReregisterPercentage% of the
expiration time (e.g., x*90% seconds).
IMS version: If value is greater than
1200 sec, the MTA will re-register 600
seconds before registration time
expires. If less than or equal to 1200
seconds, it will re-register when half of
the expiration time expires.
Register Retry
Interval
The time interval in seconds in which the SIP
Device will retry registration when the retry
interval expires, after a SIP Registration
failure, as long as the “retry-after” SIP
header field is non-zero. This behavior is also
dependent on the “Allowed for Reg. Retry”
(in section 4.1.2) configuration as this
determines if the MTA will retry registration.
Re-register
Percentage
Configure the time for the MTA to Re-
register based on the percentage of the
value of Registration Expiry Time.
