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
reproduce the current PSTN behaviour.
