5 Configuring SIP, SPCP, and NAT Configuring SIP Parameter SIP Timer D SIP Timer J INVITE Expires ReINVITE Expires Reg Min Expires Reg Max Expires Reg Retry Intvl (see Note below) Reg Retry Long Intvl (see Note below) Description FRC 3261 wait time for response retransmits. Ranges from 0 to 64 seconds. Defaults to 16 seconds. RFC 3261 Wait time for Non-INVITE request retransmits. Ranges from 0 to 64 seconds. Defaults to 16 seconds. INVITE request Expires header value. If you enter 0, the Expires header is not included in the request. Ranges from 0 to 19999999999999999999999999999999. Defaults to 240 seconds. ReINVITE request Expires header value. If you enter 0, the Expires header is not included in the request. Ranges from 0 to 19999999999999999999999999999999. Defaults to 30 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. Defaults to 1 second. Maximum registration expiration time allowed from the proxy in the Min-Expires header. If the value is greater than this setting, the maximum value is used. Defaults to 7200 seconds. Interval to wait before the Cisco IP phone retries registration after failing during the previous registration. Do not enter 0. Defaults to 30 seconds. When registration fails with a SIP response code that does not match the Retry Reg response status code (RSC) value (see next table), the SPA9000 waits for this length of time before retrying. If this interval is 0, the Cisco IP phone stops trying. This value should be much larger than the Reg Retry Intvl value. Defaults to 1200 seconds. 94 Cisco SPA and Wireless IP Phone Administration Guide
