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.
