It’s been over about 15 years since I’ve worked much with VoIP, and I’m wondering what I should buy these days. I need a physical phone at my cidery that can receive calls (from our existing Twilio-based IVR) and also make outgoing calls over SIP. I have solid wifi and can also run an Ethernet drop.
A hardware VoIP phone from Grandstream (are they still around?) or similar would work. Even better would be an ATA that supports a vintage touch tone phone that I already have. It has a physical bell ringer and I suspect not all ATAs can put out enough current to ring those.
Any recommendations on products, brands, or where to buy? Anybody have any used gear they want to trade for some cider?
