Looking for a SIP provider for my very low usage. So I’m after:
- prepaid without monthly fee, pay per unit time (no DID needed)
- security (TLS or SRTP)
- 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)
- web portals must support Tor, no Cloudflare
- (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 appreciate the suggestion, but if that’s twilio.org then I cannot reach it… it gives a 403 error. Perhaps they are tor-hostile?
btw, sorry for the late reply. I don’t check in on this acct very often.
(edit) I think this is the site:
https://www.twilio.com/en-us/sip-trunking
But gives a 403 as well.
