I don't want to waste your time , so I'll be as short as possible.
My question is : How to change the destination sip port to one of the gateways (providers). This provider listen not on standard sip port 5060 but on 5069.
I tried to set : <param name="proxy" value="provider.com:5069"/> but it doesn't work this way. Again trying to send register on 5060 (I dumped). I also searched in the web but didn't find the answer till now.
So, what is the proper way?

Thanks in advance
and Best regards
