A VoIP vendor calls firewall traversal a deployment barrier
A 2006 post by an executive at Eyeball Systems described firewall traversal as a stubborn obstacle for VoIP and IP video deployments.
Call setup and media at the edge
The author named STUN, TURN, ICE and session border controllers as familiar building blocks, but argued that endpoints could still fail when placed behind enterprise firewalls. The concern was not merely the signaling path: NAT, port mapping and media traffic could each complicate a call.
Eyeball said it was building a standalone traversal SDK and invited prospective users to identify their requirements. That proposal was a vendor initiative, not a demonstrated solution. The source makes clear why organizations wanted a predictable outcome, but supplies no independent benchmark for the proposed product.
