Advanced Voice Fields SIP page A Reg Min Expires Minimum registration expiration time allowed from the proxy in the Expires header or as a Contact header parameter. If the proxy returns a value less than this setting, the minimum value is used. Reg Max Expires The default is 1. Maximum registration expiration time allowed from the proxy in the Min-Expires header. If the value is larger than this setting, the maximum value is used. Reg Retry Intvl The default is 7200. Interval to wait before the WRP400 retries registration after failing during the last registration. Reg Retry Long Intvl The default is 30. When registration fails with a SIP response code that does not match Retry Reg RSC, the WRP400 waits for the specified length of time before retrying. If this interval is 0, the WRP400 stops trying. This value should be much larger than the Reg Retry Intvl value, which should not be 0. The default is 1200. Reg Retry Random Random delay range (in seconds) to add to Register Retry Delay Intvl when retrying REGISTER after a failure. Reg Retry Long Random Delay The default is 0, which disables this feature. Random delay range (in seconds) to add to Register Retry Long Intvl when retrying REGISTER after a failure. The default is 0, 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 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. The default value is 0, which disables the exponential backoff feature.
