Cisco Systems SPA9000 manual Response Status Code Handling, RTP Parameters

Chapter 6 SPA9000 Field Reference

SIP Tab

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 Intvl> seconds after a failure. If this feature is enabled, <Reg Retry Random Delay> is added on top of the exponential back-off adjusted delay value. This feature was added in Release 5.1.

The default value is 0, which disables the exponential back-off feature.
