Technical hitches, standards delay cable operators' adoption of VoIP

摘要

Even though cable operators have been testing voice over internet protocol since as early as 2000, they have yet to overcome technical hurdles that prevent its large-scale deployment. As a result, the first commercial cable VoIP services are unlikely to be launched before mid-2003, when updated standards-based equipment becomes available. Broadband cable operator Callahan Associates International, one of the most active proponents of VoIP, has delayed the rollout of VoIP services by a further nine months, blaming "technology-based issues" for the hold-up. The launch was originally scheduled for September last year, then postponed until December 2001 and now this autumn.
