What is a “Softswitch”?
A softswitch (a.k.a. call agent, call server or media
gateway controller) is a device that provides, at a
minimum:
• Intelligence that controls connection services for a
media gateway, and/or native IP endpoints.
• It has the ability to select processes that can be applied
to a call.
• It can provide routing for a call within the network
based on signaling and customer database
information.
• It has the ability to transfer control of the call to
another network element.
• It provides interfaces to and supports management
functions such as provisioning, fault, billing, etc.

Transport Hardware
• Software, hardware and
applications solutions typically
come packaged in a single
(proprietary) box.
• Non-standard solutions are
expensive to implement and leave
little room for innovation.
• Solutions are open standardsbased products, and can come
from multiple vendors.
• Customers are free to choose
best-in-class products to build
their network. Open standards
enable innovation and in the long
run can reduce costs

Service revenue from deployment of softswitches is estimated to be 5
TIMES greater, growing to over $19 Billion in 2004
(International Data Corporation)!

The Softswitch Potential
• New and enhanced applications
» Intelligent Networking PLUS
» Multimedia with integrated
voice/video/data
» Limited only by the imagination
• Lower barriers to entry for both
system suppliers and service providers
» Open architecture, protocols and APIs
» Leverages any/all underlying transports (packet/frame/cell)
» Dramatically less expensive development and deployment
• Greater linear scalability based on an incremental “pay as you
grow” infrastructure
• All fully interoperable with the TDM-based PSTN
7
The Softswitch Challenges
• Lots of protocols! (e.g. MGCP, MEGACO, SIP, SS7, H.323, Q.931/Q.2931,
DiffServ, RSVP, RTP, RCP, MPLS, 802.1p, etc.)
• From lots of standards bodies
(e.g. ITU, IETF, FRF, ATM Forum, IEEE, etc.)
• Being implemented by lots of players
• All chasing an evolving architecture
• Under legacy regulatory conditions
(e.g. tariffs, co-location, certifications, etc.)
• In a global marketplace
The effort needs some real
coordination to fulfill the promise!

International Softswitch Consortium
• Non-profit industry organization
• Formed in May 1999
• Promotes an open architecture and multivendor interoperability for
next-generation voice/video/data solutions
• Financed and operated by its members
• Membership now includes over 100 system suppliers and service
providers
• Already the largest consortium in the “voice-over” arena
9
The ISC Mission
To promote worldwide compatibility and
interoperability of softswitch operation
through an open membership policy, a
commitment to open standards and protocols,
sponsored interoperability events, and by
maintaining a forum for the identification,
discussion and definition of softswitch
components and functions.

Application Working Group
• Adopts interfaces for access and control of the basic and enhanced
services functions of a softswitch,
• Evaluates existing APIs and protocols to determine a suitable starting
point for an extensible softswitch services interface
• Goal is multi-vendor interoperability of services and softswitches

Architecture Working Group
• Advances an overall architecture for a softswitch that encompasses
all functions and interfaces
• Interacts with others ISC working groups to identify architectural
requirements and strategies
• Objective is softswitch independence from the underlying transport

Carrier Working Group
• Facilitates the development of a Service Level Interface that permits
end-to-end management of QoS parameters, call connection, billing and
settlement costs, and other essential functions
• Identifies necessary test processes and measurements
• Selects network/protocol analyzers that meet measurement requirements
• Goal is multi-carrier and multi-vendor interoperability of softswitches

Device Control Working Group
• Continuously reviews advancement of the MGCP
draft specification for providing input to the IETF to
identify ambiguities and desired enhancements
• May submit other proposed standards for
consideration by the IETF
• Objective is interoperability of independently
developed softswitch devices through a single, wellrecognized and clear standard
15
Marketing Working Group
• Increases general market awareness
and acceptance of next-generation
softswitch-based networking
capabilities
• Objective is to pursue on-going
promotional and educational activities
that complement the marketing efforts
of ISC’s member organizations
16
Session Management Working Group
• Effort includes set of requirements and potential protocol
tensions, long with "Best Current Practices" documents
outlining a proposed architecture, data format and
transport protocol for session-specific information
• Goal is to promote interoperability of network
management and mediation across independently
developed switching, gateway and border element devices
17
SIP Working Group
• Addresses the collaboration of multiple
softswitches, during the setup and teardown of
calls, using the Session Initiation Protocol
• Scope of work involves two essential areas:
– Signaling of packet-based IP networks
– Interworking of IP-based network signaling
with PSTN signaling
