It's very strange -- I feel the same way -- not enough discussion.

Does anyone know if voxalot supports SIPS (SIP+TLS+SDES) ? This would be a good start as at least two SIPS devicies could register and then setup an SRTP session. It would also be good to support openvpn as part of the premium plan.

People say security is difficult -- I don't buy that. There are 4 common ways to implement security: openvpn (callwithus and fonosip will do this), ipsec, zrtp (supported by zphone, twinkle, some expensive draytek devicies, and some proxies), and SIPS+SRTP (which almost every new hard phone can do).

Other thing I would say -- the huge issue is secure PSTN termination. You can with effort secure voip-voip calls today using zrtp -- but I've not been able to find anyone that will do secure PSTN termination for residential users.

What have others found about this issue? Anyone know of a secure PSTN termination that is SIP based?
