23rd March 2004 - A mass calling system from Telsis
has set a new world record by answering more than 101
million voting and competition calls in 2003, putting
the Swedish telco Telia in the record books for the
second time in two years. The system also helped Telia
take the record in 2002 with 87 million calls.
With Sweden’s population at just nine million,
it is the equivalent of more than 11 calls from everyone
in the country. The new total saw peak rates of some
1,600 calls per second being answered by Telia’s
MegaCall service in response to live television and
other interactive events. It comes after a network-wide
capacity increase by supplier Telsis, taking the system's
capacity to more than 2,500 calls per second.
Since entering service, the Telsis system at Telia
has answered a total of more than 500 million premium
rate calls. Much of the 2003 increase is being attributed
to the introduction in Sweden of a new television format,
CallTV, in which viewers compete by telephone for progressively
larger cash prizes.
Crucial to the smooth running of such events is the
way the Telsis Mass Calling system captures and stores
information entered by callers. This allows automated
selection of a cross-section of contestants who then
receive an invitation to enter subsequent stages of
a competition.
In addition to the annual records, the Mass Calling
system scored a further world first when it handled
successfully more than five million calls – the
equivalent of more than half Sweden’s population
dialling in – during a single evening’s prime
time television. But Telia’s mass calling product
manager, Stewe Wahlström, believes there is still
room for more.
“CallTV is a winning formula for interactive television
and it is vitally important that we have the technical
infrastructure in place to support it,” he says.
“For more than six years Telsis has helped keep
us at the forefront of mass calling. Yet even with the
records already achieved, the system still has plenty
of capacity for growth.”
Telsis Ocean fastIP IVR systems are installed at every
transit node on Telia’s network, making for optimum
traffic loadings and resilience. The distributed deployment
means that very large peaks of mass calls can be answered
without impacting routine voice and data traffic. Call
management and data collection is handled centrally
by a Telsis Ocean fastSCP service control point.
Mass calling places unique demands on infrastructure.
While conventional voice networks are provisioned and
configured for random call handling, mass calling creates
high volume synchronised call arrival.
Each individual Telsis Ocean fastIP IVR platform supports
up to 120 simultaneous calls, delivering the same high
quality of audio and speed of response as when handling
just a single call. Fully carrier-grade and programmable,
it holds up to 6000 hours of high quality audio combined
with dedicated DTMF and voice detection and start-at-the-beginning
playback on every channel. These and other factors make
it substantially more powerful and capable than conventional
IVR technology.
With its headquarters, research and production site
in the UK, Telsis (www.telsis.com) has sales and support
operations in France, Germany, Italy, The Netherlands,
Spain, Singapore and Australia. The company offers a
range of carrier-grade infrastructure platforms, including
intelligent SMS Routers, IN service control points,
switches and advanced IVR solutions that support a wide
variety of innovative value-added text and voice services.
Telsis products are in use with major fixed and mobile
network operators around the world.
