Abstract 

   Information Services are services whereby information is provided in 
   response to user requests, and may include involvement of a human or 
   automated agent. A popular existing Information Service is Directory 
   Assistance (DA). Moving ahead, Information Services providers 
   envision exciting multimedia services that support simultaneous 
   voice and data interactions with full operator backup at any time 
   during the call. Information Services providers are planning to 
   migrate to SIP based platforms, which will enable such advanced 
   services, while continuing to support traditional DA services.  

   Operator Services are traditional PSTN services which often involve 
   providing human or automated assistance to a caller, and often 
   require the specialized capabilities traditionally provided by an 
   operator services switch. Market and/or regulatory factors in some 
   jurisdictions dictate that some subset of Operator Services continue 
   to be provided going forward.  

   This document aims to identify how Operator and Information Services 
   can be implemented using existing or currently proposed SIP 
   mechanisms, to identity existing protocol gaps, and to provide a set 
   of Best Current Practices to facilitate interoperability. For 
   Operator Services, the intention is to describe how current operator 
   services can continue to be provided to PSTN based subscribers via a 
   SIP based operator services architecture. It also looks at how 
   current operator services might be provided to SIP based subscribers

   via such an architecture, but does not consider the larger question 
   of the need for or usefulness or suitability of each of these 
   services for SIP based subscribers.
