In the wake of the collapse of European network supplier KPNQwest and allegations of fraud at US telecoms giant WorldCom, a CMA spokesman said users could not rely on market forces alone to guarantee the telecoms supply that is vital to business.
The meeting - attended by more than 60 communications professionals responsible for managing global corporate networks - was organised in response to problems of continuity of telecoms supply brought about by the current volatile environment.
It was the first gathering in what is intended to become an ongoing campaign to put the user view of the telecoms market firmly on the agenda in what the organisations see as a changing market.
A CMA spokesman said, "The current regulatory framework is based on the assumption of a strong, vibrant global telecoms market. Times have changed and it is felt that we can no longer rely solely on market mechanisms - that events such as those recently leave users vulnerable."
Examples of actions which could be called for include giving users access to information on the financial health of suppliers and protecting customers against the consequences of unforeseen supplier collapse.
