[Freeswitch-users] sofia: call does not exist

[Christian Löschenkohl]

hello

you can find a full trace of the registration under http://pastebin.freeswitch.org/14505
the customer is behind nat and has stun enabled on his device

my theory is that the sip dialog is based on
- from
- to and
- call id

after our unauthorized respond the device changes the to header and the sofia stack do not like this
