DRG22i - Connect analogue terminals to your ToIP architecture

DRG22i is an ATA (Analogue Terminal Adaptor) providing 2 ports to plug analogue phones of faxes and connect them to the IP system as SIP terminals.

Designed for small sites, remote offices, this is the simplest way to reuse analogue terminals while deploying some telephony over IP (ToIP) solution, and retrieve the services.

DRG22i supports both basic and compressed codec: G.711, G.729A for voice and D711 and T.38 for fax.

The DRG22i is an ATA (Analogue Terminal Adaptor) meaning a gateway which allow analogue terminals (phones, faxes, modems) to be connected to an iPbx/gateway through an IP network (LAN or WAN).

This means that each of these analogue terminals is seen as a SIP terminal by the iPbx.

The DRG22i is a cost-effective solution easy to deploy in small remote branch offices, which are typically connected via a WAN/IP router to their central office network.
