Problem Sip Trunk and R6

[ipedro]

In several of my clients with R6 they are losing the capacity of find the public ip through stun server, and they can't make calls through a sip provider.

it appends unexpectedly. and one times, in one client, it started working correctly, without making any changes. And in another client when i upgraded to R6 few days later i had the same problem.

I made a trace an the result is:
