Is it possible to create VPN tunnels to remote users that connect dial-up to different ISPs and have VoIP traffic in the tunnel? If this is possible, how will the encryption process affect the performance of the VoIP traffic if I use, for example, the G.723 codec that requires 6.3kbps? How does it scale?
Also, I currently have Cisco AS5300s and 3640s routers. Can I use these as the central device by purchasing an optional module/card or do I have to purchase another device?
