Welcome to Voxilla's Certificate Authority Service for Linksys Analog VoIP Adaptor users.

This FREE service generates an SRTP (Secure Real Time Transport) certificate for a Linksys analog telephone adaptor and enables encrypted VoIP calls with another party who also has a certificate from Voxilla.

Encrypted calls can be made with direct connection or providers that support peer to peer connection like Free World Dialup and IPTel. Voxilla's SRTP certificate will not encrypt calls made to the PSTN system, or to VoIP services such as Vonage or VoicePulse. To make a secure call after Voxilla's SRTP certificate is installed, dial "*18" followed by the phone number. If you hear three unique tones after dialing, your connection is secure.
