Goals
Currently, the SR140 does not pass the SIP Request URI information to the application. It does appear in the ECC log, so it gets to our SIP stack. Customers sometimes want the part with the number@ip_address (e.g. "1111@10.160.110.201" here) because it is different from the rest of the information in the SIP INVITE. Normally, the called number (sometimes incorrectly called the DID) is provided in the To: field in the SIP INVITE message and that's what we pass up to the application. (In fact, the To: field is a SIP header and an application can get all SIP headers.) Sometimes though, usually if a call gets forwarded, the called number will be reflected in the SIP URI though and not the To: field. We do not currently pass the SIP URI up to the application and so as a feature request, we would be looking to make the Request URI accessible to the application.

| # | Title | User Story | Importance | Notes |
|---|---|---|---|---|
| 1 | Add an entry to the beginning of the SIP INVITE header list for the SIP URI value from the SIP INVITE. The complete SIP Request URI value string i.e. 1234@dialogic.com:5060 will appear after the name of the new entry. The name of new entry will be Request-URI. i.e. Request-URI: 1234@dialogic.com:5060 | As a user, I would like to know the SIP URI value, so I can determine the original phone number of a call that was forwarded. | High | This information will be present for the application to use after the BfvLineWaitForCall API function call returns. The user will need to malloc memory for the sip_header_list member of the structure args_telephone in order to receive both the SIP URI value and the headers from the SIP INVITE. The user will need to parse the SIP INVITE headers list to get the SIP Request URI. |
| 2 | This feature will not change the current behavior for the CALL_RES called_party_number value. | High | This feature should also not impact or be aware of the diversion values. | |
