It was found that freeswitch performs multiple INVITES. But
why?
One reason why multiple invites are sent out is if FreeSWITCH
doesn't receive anything back. This could mean the far end is down
for some reason or that there is a network issue between FS and
the other endpoint. NAT is a common issue in this sort of
configuration. I recommend that you look at SIP traces on each end
of the SIP dialog.
