Telephony Service Features

Reliable Internet Telephony Service bundled together with In-Confidence applications
Strictly pass through service - no encryption/decryption at the switch
*571-bit ECDH is currently equivalent in security to 15,360-bit RSA/DH/DSA (based on table 1, RFC 5349 standard; Therefore, SecureGSM's triple ECDH is approximately equivalent to 3 x 15,360-bit = 46,080-bit RSA/DH/DSA.
