Are there VOIP to PSTN providers that support encryption?
My thinking is that calls on the PSTN have legal protection against wiretapping. Such protection is weak or nonexistent for an SIP connection between my computer and the PSTN provider's server. So it is worthwhile to encrypt between my computer and the server, even though the unencrypted signal is transmitted from the server over the PSTN.
None of the listings of providers that I have seen indicates whether they support TLS or SRTP. I've used Diamond card, but as far as I can tell they don't encrypt.
