The Grandstream HT813 is an Analog Telephone Adapter (ATA) designed for connecting traditional analog phones to VoIP services. They do not provide internet connectivity or act as standalone routers. To use them, you must have an active and compatible VoIP service.

Before you buy please contact your VoIP Service Provider to ensure that your provider supports the ATA and can supply the necessary SIP credentials.

These details must be obtained from your provider.
