    8. aHIT! Activity Group has approved the list of VoIP Applications as part of its work plan for 2000. The goal is to develop Interoperability Requirements Document for each application by year end. These applications are: .Billing & Authentication / Authorization / Accounting: In order to achieve similar service capabilities as those prevalent in the circuit switched network, packet telephony providers must establish appropriate standards for settlement of inter-carrier services. In order to effect this, all inter-carrier authentication, authorization, and accounting/billing functions must be specified. 2. Fax over IP (FoIP): Fax services currently comprise over 30% of long distance calls. Supporting fax services in the packet environment has been the subject of significant standardization efforts, but significant additional work remains to implement FoIP with value added features (e.g. fax to e-mail addresses; fax on demand; integration of fax with conferencing), especially in a multi-vendor, multi-carrier environment. Interoperable standards like T.38 will be essential, as this provides greater efficiency and more reliable fax transport than G.711 solutions. 3. Internet Call Waiting: For users that access the Internet over dialup, call completion during the online session is typically prohibited without the installation of a second line. A number of solutions have been developed that notify the user of an incoming call and allow the user to take the call. With packet telephony solutions, internet call waiting allows a customer to take the call without interrupting the online session. 4. Audio Conferencing: With the support of toll-quality telephony, call services in the packet network will be extended to include multi-party calling and conferencing applications. All enabling capabilities in terms of call setup and management as well as billing and authorization must be extended to support conferencing between an arbitrary number of participants of an arbitrary number of packet telephony networks.aHIT!
