[Freeswitch-users] Using Sofia-SIP with ICE NAT Traversal Mechanism

Hi, I know that FreeSWITCH uses libdingaling to talk to Jingle call parties. Also I know that Jingle Protocol uses ICE protocol to traverse NAT devices. So : does libdingaling use an open library such as libnice for ICE? Is it possible to use the ICE implementation in Sofia-SIP endpoint? If not, how could I integrate an open ICE library in Sofia-SIP?
