Deutsche Telekom to launch voice-over-IP trial

Delivering on its pledge earlier this year to invest in Internet telephony, Deutsche Telekom AG will initiate a pilot Internet telephony service later this year using networking products from Ascend and VocalTec. The 'PC-to-Phone' pilot service will let 1000 Deutsche Telekom online and Internet service subscribers make international calls using Voice-over-Internet Protocol (VoIP).

Delivering on its pledge earlier this year to invest in Internet telephony, Deutsche Telekom AG will initiate a pilot Internet telephony service later this year using networking products from Ascend Communications and VocalTec.

The "PC-to-Phone" pilot service will let 1,000 Deutsche Telekom online and Internet service subscribers make international calls using Voice-over-Internet Protocol (VoIP), according to Ascend. The service will provide VoIP connections from Germany to the Netherlands, Switzerland, Australia, Hong Kong, Japan, Singapore and North America.

To make a VoIP call, users will dial the desired number via a multimedia PC, which will translate the call into IP packets and direct them to the nearest Deutsche Telekom point-of-presence, the statement said. At the call's destination -- for example, New York -- the VoIP gateway, using Ascend's MAX 6000 WAN access switch, will convert the IP packets back into voice and forward the call to the public telephone network, the statement said. The public network will deliver the call to the call recipient's telephone, which can be picked up in standard fashion, it said.

VocalTec, which is based in Herzliya, Israel, will contribute its Ensemble Architecture products to the pilot, according to a statement from VocalTec, which is partly owned by Deutsche Telekom.

Ascend Communications, with headquarters in Alameda, California, can be reached on the World Wide Web at http://www.ascend.com/. VocalTec can be reached on the World Wide Web at http://www.vocaltec.com/.
