ATA Design Features

VOCAL includes all the standard features expected of an ATA, plus innovative premium features demanded by your customers. With the patent-pending VOCAL VoATA control software, an end user can manage up to four VoIP service providers with a single ATA. User access may be automatic on a per-number basis, or can be as simple as using a standard long distance prefix such as “1010825…”. Contact us to discuss your application design requirements.
