Hi *,
Here is the trace. One thing I have noticed is that the 180 Ringing being
returned from the Snom phone (behind the NAT) contains the contact header
still with the private IP (192.168.1.100). Theoretically though I don't see
how this can affect the transaction handling - maybe you can shed some
light.
