Analog Telephone Adapters (ATA's for short) are used to connect existing analog telephones to an IP network, such as ours, at a very low cost.
While they cannot be used to connect analog or digital phones that were previously connected to an on-premise PBX, in some cases, we can use the Grandstream GXW-40xx series to provide service to an existing on-premise PBX system.
