Analog Telephone Adapters

Grandstream analog telephone adapters (ATAs) convert traditional analog phone lines to VoIP interfaces. They enable legacy devices like fax machines or analog handsets to operate on modern IP networks, supporting reliable voice communication across platforms. With advanced codec support and security, these adapters help reduce infrastructure upgrades.
ISP Supplies carries a full range of Grandstream ATAs to facilitate seamless analog-to-digital integration in telephony systems.
