           IPX Portfolio Over A Single, Cost-Efficient Interconnect

AMSTERDAM -- November 12, 2012

iBasis, a KPN company, today announced that it will use the AMS-IX Inter-IPX
service as part of its strategy to extend the reach of its IPX product
portfolio. AMS-IX offers iBasis a secure and efficient one-stop shop to
interconnect to other IPX providers and exchange voice and data services.

The open interconnect solution provided by AMS-IX allows iBasis’ customers to
peer IP traffic with other mobile networks and achieve significant operational
cost savings by bundling multiple services over a single, managed interconnect
in one facility. The mobile services initially supported by iBasis over the
AMS-IX Inter-IPX service include Premium Voice IPX, LTE signaling, GRX, and
Sigtran.

AMS-IX was the first to introduce a service focused on IPX providers faced
with the challenge of a future in which the distinction between mobile and
fixed networking will gradually disappear. The service offers a place where
regional and neighboring IPX networks can efficiently link to each other and
cover more territory, content and volume. The Inter-IPX service complies with
the high quality standards required by GSMA and includes an Inter-IPX SLA.

The combination of the critical mass of business partners, the stable all-IP
environment, the historical success of the AMS-IX GRX service, and this new
carrier grade Inter-IPX SLA option led iBasis to select the AMS-IX Inter-IPX
solution. “AMS-IX not only offers us a single point where we can exchange
multiple services quickly with many different mobile operators, it also gives
us guaranteed end-to-end quality of service through the Inter-IPX SLA,” said
Chris Lengyel, iBasis Director of Strategic Marketing and New Products.

“We are pleased that iBasis has chosen to connect to our Inter-IPX service and
in this way recognizes the value of this service for its organization and
end-users,” says Job Witteman, CEO of AMS-IX. “With its innovative and high
level of service iBasis is a valuable addition to our Inter-IPX community.”
