[Freeswitch-users] bridging two outbound calls

Mystery solved! I did not open UDP port 16384-32768.
I thought I have done that, but apparently took it away (or created a
new instance somewhere along the way). Re-opening the ports makes the
bridging call happy. Thanks for your help, Steven, Peter.
Apparently conferencing outbound calls only generates outbound RTP
traffic which can still work even without those ports open.
Cheers.
