There is no STUN involved, i set the static ip instead.

I have some new information from my provider. They say, the problem is with
the interoperability; they are using asterisk and the problem starts when
sipx sends the ringback tone. their server doesn't register the call for
10-15 sec and it doesn't open the signal.
or something like this.
when i set the call to go directly to the operator, they sad it was fine,
because there was no ringback tone involved.

is there a way to get this solved?
