The sad reality is that POTS is dying. The upside of this is that in principle we don’t need a VOIP provider, right? We should be able to run our own SIP server and place a call to another SIP user without using a POTS line -- thus w/out a subscription to a service. SIP addresses look like email addresses.

The problem is, IIUC, I have no way of knowing the SIP address for my bank. I only have their phone number. Is there a way around this? Is there a way to obtain the underlying VOIP address for a phone number?

Looking for a SIP provider for my very low usage. So I’m after:

1. prepaid without monthly fee, pay per unit time (no DID needed)
2. security (TLS or SRTP)
3. caller ID control (I have no inbound voice line; I have an inbound fax line I prefer to use; freetyping CID info nanny-free is the best)
4. web portals must support Tor, no Cloudflare
5. (not critical) support for lightweight codecs like speex, gsm, or bv16

The closest provider to satisfying that criteria I’ve found so far is leap.tel, but they lack TLS/SRTP and only support G.711. DID Logic supports TLS/SRTP, but they only have plans with monthly fees.

I have had no problem using VOIP over #protonVPN until recently. Connections happen but there is no audio. Anyone notice this?

I wondered if maybe they decided to make VOIP a non-free feature, but their premium plans do not list VOIP as an extra feature.
