Keep it, or make your own?
Whether this is something you could build for yourself with an AI app builder, and what you would give up.
Keep it
To replace NFON you would be making phone numbers and calls carried over the phone network. That is not a weekend's work, with an AI app builder or without one.
That makes this kind of software worth paying for, not this one in particular: 50 of the 77 other business phone systems grade higher. It costs $91.16 a year.
What you could not
- Phone numbers and calls carried over the phone network.
- Video calls.
- It is priced for each person, which means accounts and billing for a team.
- AI features, unless you pay a model provider for each request yourself.
What this rests on. NFON’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
