You probably want to start out adding a user to the subscriber table. They syntax is shown below: openserctl add <username> <password> <email> rpid is the Remote-Party-ID and is a SIP header. This is defined in the following EXPIRED draft: http://tools.ietf.org/html/draft-ietf-sip-privacy-04 There are others on this list that might know what the current status of this header is. You may also want to research the P-Asserted-Identity (RFC3325) SIP header. There is a lot of documentation on the openser.org web site. Regards, Norm Live Great wrote:
