Open-Source SIP Soft-Switch with External Call Control
Capabilities
March 11, 2006, Raleigh, NC.
We
are pleased to announce the first public release of SipExchange.
SipExchange r0.0.1a
is an Alpha release to give users a preview of the
system.
SipExchange is an open-source softswitch that provides
standard SIP services like registration, proxy and presence. Using
the
SipExchange application, service providers can offer telephone services
to their subscribers as well as other services based on voice, video
and instant messaging. SipExchange supports many of the standard
subscriber features offered by the traditional
telephone exchanges and PBXs. In addition, SipExchange supports
external call
control capabilities using which service providers and software
developers can create new features and
services rapidly and plug them into the SipExchange application.
The following are the highlights of the release.
Registration service: On SIP registration, the system
authenticates the subscribers and stores their locations for routing
inbound call sessions.
Proxy service: Supports SIP to SIP call session setup and
tear-down. Inbound calls to SipExchange subscribers are routed to the
subscribers' current locations. The service also allows subscribers to
make outbound calls to other subscribers and non-subscribers.
CDR generation: The SipExchange server produces call detail
records (CDRs) and stores them in the database for billing and
reporting
applications.
External call control: The basic framework for external
call control using IN/AIN-like triggers is included.
Web-based administration and reporting: System
administrators can administer SIP domains and subscribers. They can
also tune system parameters and manage CDRs. The reports allow the
system administrators to view user locations and CDRs.
