Hi There,
I will try to bump up this question one more try.
Generally, if you use TCP transport on port 5060 - there is no problem.
However, if you try to change the port, the you get into troubles.
Details are below in my previous emails.
If someone could help - will be much appreciated.
Thanks,
Filip
