International telephone numbers

International inbound numbers provide your company with an immediate presence overseas and extend the availability of your service further. They can enable your business expansion to new regions and markets at minimal costs.

Your customers abroad only incur local charges when calling your International Direct Dial Numbers (DDI) and the calls are automatically forwarded directly onto the Daktela system. Any customers calling your International Toll-Free numbers do not incur any call charges at all. As with the above these are automatically forwarded to the underlying UK numbers on the Daktela system.
