Cisco PenTeleData 8800 Series Guide

DescriptionParameter
Maximum value of the exponential delay. The
maximum value to cap the exponential backoff retry
delay (which starts at the Register Retry Intvl and
doubles every retry). Defaults to 0, which disables the
exponential backoff (that is, the error retry interval is
always at the Register Retry Intvl). When this feature
is enabled, the Reg Retry Random Delay is added to
the exponential backoff delay value. The range is from
0 to 2147483647.
Default: 0
Reg Retry Intvl Cap
Sets the lower limit of the REGISTER expires value
returned from the Proxy server.
Sub Min Expires
Sets the upper limit of the REGISTER minexpires
value returned from the Proxy server in the
Min-Expires header.
Default: 7200.
Sub Max Expires
This value (in seconds) determines the retry interval
when the last Subscribe request fails.
Default: 10.
Sub Retry Intvl
The phone can use a RETRY-AFTER value when it is received from a SIP proxy server that is too busy to
process a request (503 Service Unavailable message). If the response message includes a RETRY-AFTER
header, the phone waits for the specified length of time before to REGISTER again. If a RETRY-AFTER
header is not present, the phone waits for the value specified in the Reg Retry Interval or the Reg Retry Long
Interval.
