Voice over IP

VoIP → Voice over IP

Open discussions about VOIP protocols (e.g. SIP), providers, and related security matters.

There are two other VOIP communities on big centralized instances (thus kept unnamed), and ATM they are rightfully dead communities anyway. This infosec.pub community is apparently the only free-world decentralized threadiverse venue for VOIP chatter -- but if another emerges let the moderator know so it can be linked in this sidebar.

    SIP provider suggestions (TLS or SRTP, payg)

    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.

    Did protonVPN recently start blocking VOIP?

    cross-posted from: https://infosec.pub/post/9382315

    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.
