The Grandstream HT813 has 1 FXS port to connect an analog telephone and 1 FXO port to connect your PSTN landline. Thanks to its FXS and FXO port, you can now automatically and without any cost transfer your calls from the landline to a voip switchboard and make calls with your landline using an extension of your voip switchboard. You will be able to continue to benefit from all the services which offer your landline, but also the innovative functionalities of IP telephony.

In addition to its ability to convert analog technology to Voip, it also allows you to make calls with a SIP account to take advantage of excellent voip rates.

This extraordinary hybrid ATA is a flexible device that offers HD voice quality, a high-end security system and multiple automatic provisioning options. The virtual switchboard offered by Hivoox Telecom is fully compatible with this adapter and together they allow the user to benefit from very high quality voip service.

With this adapter, you are sure to never lose an important call, because in the event of a power cut, your traditional landline will continue to function without any problems.

How it works?

To configure this adapter, you must use 2 SIP accounts or extensions from your voip switchboard and connect your landline to the line port on the device. When you receive a call on the landline, it is automatically transferred to the sip account configured for this purpose. You will then receive the call on the device, where you configured the destination sip account, without any geographic limit.

To make a call, you can use your sip account, or an extension of your voip switchboard, to call the extension configured on the device and hear the tone of the landline, which will allow you to dial your number. Using the virtual switchboard of Hivoox Telecom, you can also make calls with your voip line at more economical rates.
