feature was added in Release 5.1.

Random delay range (in seconds) to add to <Register
Retry Long Intvl> when retrying REGSITER after a failure.
This feature was added in Release 5.1.
Defaults to blank, which disables this feature.
Reg Retry Intvl Cap The maximum value to cap the exponential back-off
retry delay (which starts at <Register Retry Intvl> and
doubles on every REGISTER retry after a failure). In other
words, the retry interval is always at <Register Retry

<Reg Retry Random Delay> is added on top of the
exponential back-off adjusted delay value. This feature
was added in Release 5.1.
Defaults to blank, which disables the exponential back-
off feature.
Sub Min Expires This value sets the lower limit of the REGISTER expires
value returned from the Proxy server.
Sub Max Expires This value sets the upper limit of the REGISTER min-
expires value returned from the Proxy server in the Min-
Expires header. Defaults to 7200.
Sub Retry Intvl This value (in seconds) determines the retry interval
when the last Subscribe request fails. Defaults to 10.
