Hello everyone, I have a fortigate 30E firewall device and 3cx is installed in Hyper V. My problem is with android softphones. I am having different kinds of problems such as audio cracking, volume level dropping spontaneously, registration failures, soft phone users often complaining that they pick up the phone but there is no audio in or out etc. These are the problems that i am encountering both locally and via 3g/ 4g. How can i fix this? Thx in advance.
