Actually it isn't necessarily needed.

If two parties establish a bidirectional stream (which in the case of a
voice or video call they will), then each endpoint's outgoing packets to
the other endpoint will punch a hole in its firewall that allows the other
endpoint's packets to come in, and you don't need ICE for anything.
