[fw-wiz] VOIP in the field today



I've been away from this topic for a while but am curious.

Has any progress has been made in deploying VOIP without having to use underlying security protocols (SSL/TLS or IPSEC) to secure the VOIP signaling and media streams?

Are any folks using network edge devices to secure VOIP, e.g., "VOIP-aware" firewall or secure voice proxies? Are you complementing these with MAC level encryption from endpoint-to-proxy/endpoint-to-edge? begin:vcard
