Good afternoon,
I have the zoiper app installed on my motorola cell phone and I need to make calls to a SIP server that is inside my lan but in the middle it has a sonicwall TZ 215 firewall
In our server we use only port 4360 and I need to know which exact ports to open on my firewall so I can make the connections work ... today I can log in but I have problems with only one audio or none
I need to solve it urgently, please
