[Freeswitch-users] OT: Apple goes to great lengths to defeat NAT and firewalls with new Facetime

[Kristian Kielhofner]

Somewhat off-topic but because it comes up here regularly.

Wondering why the FS developers default to not including rtpmap lines
for statically defined RTP payload types?

Wonder why SIP signalling over TCP or TLS is much more reliable
through various NAT and firewall devices?

Apple has put a significant amount of effort into redesigning Facetime
to better handle NAT and firewall devices.  More details here:

I wonder if FS could multiplex SIP and RTP over the same port someday?
 Maybe support deflate encoding?
