0x2957 SIP Request URI User Information Qualifier

Use this TLV to append a user-defined ASCII string to the Request URI user name in outbound SIP calls from the Excel platform. Specifically, the ASCII string is populated in the user information of the Request-URI header in the outbound SIP INVITE message.

When the Excel platform is in a SIP/PSTN gateway environment, you can use this TLV to report the terminating trunk group information in a
PSTN-to-SIP call.

If the host provides the Request URI parameters, it must also provide the "To Header" parameters. (See TLVs 0x2919, 0x291A, 0x291B, and 0x291C).
