What types of telephones work with the VoIP ATA?
Any regular touchtone phone in your home or office can be used with your VoIP service. Corded or cordless phones work equally well, and multi-line regular phones also work fine. Most older office phones have proprietary, digital signaling, and don’t work if connected to a VoIP device. The only way VoIP can work with these older key systems or PBXes is by connecting a multi-channel VoIP device between the central brain of the phone system and a high-bandwidth Internet circuit.
