Chapter 5 Linksys ATA Field Reference SIP Tab SIP Timer H INVITE final response, time-out value, which can range from 0 to 64 seconds. The default is 32. SIP Timer D ACK hang-around time, which can range from 0 to 64 seconds. The default is 32. SIP Timer J Non-INVITE response hang-around time, which can range from 0 to 64 seconds. The default is 32. INVITE Expires ReINVITE Expires INVITE request Expires header value. If you enter 0, the Expires header is not included in the request. The default is 240. Range: 0-(231-1). ReINVITE request Expires header value. If you enter 0, the Expires header is not included in the request. The default is 30. Range: 0-(231-1). 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. The default is 1. Reg Max Expires 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. The default is 7200. Reg Retry Intvl Interval to wait before the Linksys IP phone retries registration after failing during the last registration. The default is 30. Reg Retry Long Intvl When registration fails with a SIP response code that does not match, the Linksys IP phone waits for the specified length of time before retrying. If this interval is 0, the Linksys IP phone 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 Delay Random delay range (in seconds) to add to when retrying REGISTER after a failure. This feature was added in Release 5.1. The default is 0, which disables this feature. Reg Retry Long Random Delay Random delay range (in seconds) to add to when retrying REGSITER after a failure. This feature was added in Release 5.1. 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 and doubles on every REGISTER retry after a failure). In other words, the retry interval is always at seconds after a failure. If this feature is enabled, 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. Document Version 3.2 Linksys IP Phone Administrator Guide 5-13
