ICE: the ultimate way of beating NAT in SIP

in English by Saúl Ibarra Corretgé of AG Projects at AMOOCON 2010

Abstract

We all know NAT is one of the worst issues SIP is facing.

Interactive Connection Establishment (ICE) was born in order to fix this and help devices talk to each other traversing every type of NAT our there.

However ICE is a complex protocol and doesn’t work with the traditional NAT traversal scenarios.

The talk will go through the problem of NAT in SIP and deeply explain ICE protocol and what changes were done in OpenSIPS and MediaProxy in order to make it work.

After there will be a short live demo showing every component involved and demonstrating how and why ICE works.
