Currently (Nov 2017) successfully use a BT Falcon VoIP handset with BT Hub 5, a low cost method of making telephone calls. The Falcon is assigned a VoIP telephone number, with a local dialling code alias for incoming calls. That geographical number is separate from my landline telephone number.
BT have stated Broadband Voice will cease on 1st Dec 2017.
Can anyone recommend an alternative low cost solution, please ? I'd like to keep at least the local telephone number and would prefer not to have to use a headset/microphone connected to a computer.
Plenty of basic VOIP service providers out there ... although you might need new hardware if te Falcon cannot be reconfigured.
I use a Gigaset S850A-GO which has a single PSTN and six VOIP line capability along with up to six handsets and includes an answer machine.
