                 http://www.fokus.gmd.de/events/iptel2001/

Objectives
----------
Internet telephony is rapidly evolving from research to design
and deployment. The objectives of the IP Telephony Workshop are
to bring together researchers, developers, vendors and service
providers active in this area and stimulate discussion on
innovation, research, implementation, deployment experiences and
future directions.

Scope & Topics
--------------
Original technical articles related to IP telephony are solicited.
Only papers with significant technical content, not "white papers"
or tutorials, will be considered for publication:

     - Research papers (unique ideas, novel algorithms,
       architectures, measurements, theoretical and/or analytical
       contributions)
     - Surveys, state-of-the-art studies, technology comparisons
     - Implementation and deployment reports
     - Standardization reports

Particular areas of interest include, but are not limited to, the
following:

     - Integration with Internet services (e.g., web, instant
       messaging, games)
     - Added-value services (e.g., call centers, conferencing)
     - Mobility and 3rd generation wireless
     - Authentication, authorization, accounting, charging,
       settlement
     - QoS support
     - Security (e.g., privacy, authentication, certification
       authorities, firewall traversal)
     - Call signaling & processing
     - Feature creation
     - Supporting services (e.g., call routing, lookup services)
     - Audio & video encoding and transmission
     - Management and provisioning
     - Interworking with the PSTN
     - Design and deployment considerations (e.g., performance,
       scalability, reliability)
