Diversion Header Support:

If you enable this feature, SS7 Redirection information will be sent in the SIP Diversion Header in the outgoing SIP INVITE. See SIP Diversion Header for more information.

Disable (default) - No redirection information will be sent.

Diversion - SS7 Redirection information will be sent in the SIP Diversion Header in the outgoing SIP INVITE.

CC-Diversion - Along with the SIP Diversion Header information, the CC-Diversion header field enables the IMG to pass call control redirecting information during the call setup. Call control redirection is the redirection of a call based on a subscriber service such as call forwarding.

History-Info - The IMG will insert the SIP History-Info Header into the outgoing SIP INVITE.

Time Stamp Support:

Enable - The IMG will insert the Timestamp Header in the format of: Timestamp: MMDDYYYYHHMMSS. This value is derived from the system time of the IMG. (After bootup the IMG uses Jan 1,1970 as its internal date or receives a proper value for the time through SNTP)

Disable - The IMG will not insert the Timestamp.  However, actions based on the Timestamp are in accordance with sec 8.2.6.1 of RFC 3261
