3.2.5.3.  Minimal Profile

   A client falling into the 'Minimal' profile will send/receive RTP
   form the same IP/port combination.  This client requires proprietary
   network based solutions to function in any NAT traversal scenario.

   All clients SHOULD support the 'Primary Profile', MUST support the
   'Minimal Profile' and MAY support the 'Consumer Profile'.

This suggests that there is such a solution for dealing with boxes 
which only support a minimal profile. I would greatly appreciate it
if someone can enlighten me in this area. I can see how to do it without
any endpoint involvement if the IAD supports both symmetric RTP _AND_
symmetric signaling. Can anyone describe a solution without proprietary
requirements on the IAD which functions without symmetric signaling
from the IAD? 

Appreciate any thoughts in this area.

Thanks and cheers,
Shaun Bharrat

A new version of the NAT Scenarios has been submitted.  Until it appears in the archives, you can get a copy from http://www.ubiquitysoftware.com/ietf/draft-ietf-sipping-nat-scenarios-05.txt and http://www.ubiquitysoftware.com/ietf/draft-ietf-sipping-nat-scenarios-05.html.

 

This version is still a work-in-progress with the view to having an ‘early’ completed version post Montreal.  All feedback is welcome, especially on the scenarios section as we try to compile a wide ranging and useful list of deployment scenarios.  New suggestions welcome.

 

Best Regards,

 

Chris.
