Voice over IP

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.
