Grandstream Gateways & ATAs
Grandstream gateways are a cost-effective solution for organizations switching to VoIP. With a media gateway, you can continue to use your legacy equipment even after the switch to VoIP communications. Grandstream ATAs (analog telephone adapters) are cost-effective devices that convert between analog and IP signals.
