Today, a SIP user wanting to charge for a service needs to establish an agreement with all prospective callers. This administrative overhead can be avoided if caller and callee can prove the duration and existence of a call in case of a dispute. The draft describes requirements for protocols and SIP extension that can be used to implement such functionality.
