If you are going to recommend users connect to you via a proxy or Tor, don't recommend tor2web. The whole point of tor2web is that it's a non-anonymous way to access Tor. Your traffic goes through tor2web servers, which are not part of the onion routing.

Anyway, nice business. If I'm understanding correctly, you are basically an SIP hosting provider that assumes your clients will use Linphone to connect. Am I correct in this? If so, it's an interesting model, but I think you need to put more effort into clarifying that you are a host, not a security provider. Also, you might want to apply some of that hosting expertise to your website....

Hm. I'm not sure I get it. (from the Google cache)

So it's a ZRTP SIP provider that uses regular phone number format as the identifier? It strikes me as rather much like OSTN/OSTel, but using a phone-number-looking identifier rather than a username... and if that's the case, the whole ostn stack is opensource/auditable and federated, so I'm unsure of the improvement here, aside from the branding. Heck, I would prefer if they used the OSTN chef cookbooks and contributed back.

EDIT: Nooo! I'm the downer top commenter! I have become all that I am mildly irritated by. To clarify, I like that this service was created, and commend the interest of the devs, regardless of my outstanding questions :)

So by registrating I get (1) a number, (2) a password, and (3) a country code. What do I enter as username etc. in Linphone?

presumably the country code + phone number is your username... but I can't see the tutorial videos while the site is struggling

Site seems dead. Is it free software? What differentiates it from Signal/TS?

* It is free software, or rather, the client they recommend is Linphone, an existing open-source VoIP client. * Specifically, the value add is an introduction/routing layer over SIP. They recommend connecting via Tor. * The encryption is stock ZRTP.

In comparison, Signal/TS is free software, but uses novel crypto for text messages. I believe RedPhone/Signal voice is still just ZRTP. RedPhone/Signal will convert the SAS code to two frequently-amusing phrases, whereas LinPhone will just display the raw code.

There doesn't seem to be an easy way to use RedPhone with Tor, or to anonymously register with RedPhone, though I could be wrong.

I've tried both with and without the country code, but the SIP client fails to register. The server could be overloaded, tough — perhaps I should try again tomorrow.
