0x2923 NPDI SIP From User Name

In a Request for Service message and PPL Event Indication, this TLV provides information parsed from the "From" header field of the incoming SIP message (for example INVITE or REGISTER). This TLV could be used in a Route Control message to specify the local User Agent’s addressing information, which would be used to create the "From" header for the outgoing SIP message.

Use this TLV to specify a user name in the "From" header.
