SigmaCom was established in 2000 and is seated in the Netherlands second
largest city: Rotterdam. Historically, the company has ties with TTM
Nederland, which was an important Dialogic toolkit vendor back in the early
90's. After a merger in 1999 TTM was renamed !Effective, and the Computer
Telephony division was split off to become SigmaCom.

SigmaCom provides the complete range of Computer Telephony products supplied
by Dialogic, Gammalink and Parity Software (now all Intel companies) for
developers, system integrators and VAR's all over the world.
In the Netherlands, SigmaCom also is the authorized distributor for the
German Unified Messaging and CTI manufacurer, serVonic GmbH and JUSAN, the
Spanish manufacturer of low-cost voice response systems. These products are
all sold via PABX vendors and System Integrators.
