one. Additionally, some devices will act as both UAC and UAS for a single transaction; these are called Back-to-Back User Agents (B2BUAs).[1]:p20 SIP responses specify a three-digit integer response code, which is one of a number of defined codes that detail the status of the request.

It also includes SIP response codes defined in obsolete SIP RFCs (specifically, RFC 2543), which are therefore not registered with the IANA; these are explicitly noted as such.
