Good Afternoon All
Apologies if some of my questions on here are very basic but I have some queries which my googling hasn't been able to answer. I am thinking of switching us over to VOIP as we're in the fortunate position of having FTTP but our copper landline is abysmal and still required on occasion. I want to switch us over to VOIP for quality and stability reasons but I wonder if someone can answer the following questions:
1. If I move my number to VOIP, I believe I cannot move back. Is this likely to change in the future when the PSTN network is turned off (i.e if I move from BT who don't offer VOIP to residential customers now, is it likely they will in the future?)
2. Our house is old and the BT phone extension wiring is fairly new. Is there a VOIP service which would allow me to plug an ATA into the 'master' socket and use normal phones through the extension wiring?
3. If someone is on the phone (as with a traditional landline) and someone picks up another VOIP phone, will they hear the conversation as now or not?
