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

Wed Sep 23 08:53:52 PDT 2009

libdingaling does not do the gtalk ice stuff, mod_dingaling does by using
utils in the FS core.
We have stun client code, random string generators in switch_utils.c and
settings in the rtp stack to send and recv authed stun packets using the
aforementioned functions mixed in with the audio.  Whatever you have to
change will have to be added to FS core and it cannot be with any lib that
depends on glib or it would make our core depend on glib which is not going
to happen because it would make support on windows a nightmare.
