account.X.reg_failed_retry_min_time
[1]
It configures the base time to wait (in seconds) for the IP phone to retry to re-register
account X when registration fails.
Note: It is used in conjunction with the parameter
"account.X.reg_failed_retry_max_time" to determine how long to wait. The algorithm is
defined in RFC 5626. We recommend you to set this value to an integer between 10 to
120, if needed. If the values of this parameter and the parameter
"account.X.reg_failed_retry_max_time" are set to 0, the interval configured by
"account.X.reg_fail_retry_interval" will be used.
Integer greater than or equal to 0
account.X.reg_failed_retry_max_time
[1]
It configures the maximum time to wait (in seconds) for the IP phone to retry to
re-register account X when registration fails.
Note: It is used in conjunction with the parameter
"account.X.reg_failed_retry_min_time" to determine how long to wait. The algorithm is
defined in RFC 5626. We recommend you to set this value to an integer between 60 to
1800, if needed. If the values of this parameter and the parameter
"account.X.reg_failed_retry_min_time" are set to 0, the interval configured by
"account.X.reg_fail_retry_interval" will be used.
Integer greater than or equal to 0

X is the account ID. For T54S/T48S/T48G/T46S/T46G/T29G, X=1-16; for T52S/T42G/T42S, X=1-12; for
T41P/T41S/T27P/T27G, X=1-6; for T40P/T40G/T23P/T23G, X=1-3; for T21(P) E2, X=1-2; for T19(P) E2, X=1.
