Aastra’s Dialog 4200 series of digital telephones com-
bines excellent sound quality with superior ergonomics
and outstanding features. In addition, users benefit from
advanced technical implementations such as built-in
acoustic shock protection and hearing-impaired support.
Digital telephones have from the start been developed as
an integral part of Aastra’s communication systems. The
functionality of these telephones has grown in parallel with the
development of the call servers. Today the digital telephones
are fundamental components in the creation and the delivery
of telephony services to users within the organization, as well
as to users outside of the organization. Through deployment
of digital telephones in combination with the Aastra call
server, the full power of Aastra’s communications server
can be achieved. As users have different jobs and thereby
different communication needs, Aastra provides a range of
telephones in order to match demands on functionality, size,
price and design. No matter which telephone you choose,
the Aastra design assures high quality and top performance.
