Call no voice both side after pickup 30s

[Tony_Lin]

This issue happend in our client 3CX server once a week.

The phenomenon is: voice is good when call pick up, but it will no voice both side in seconds.

We will upload a recording file in attachment, you can hear that both side no voice in 30s. But agent and customer still talking.

We not sure where problem is, 3CX, webclient or SIP Trunk.

this looks like it would need troubleshooting from our support team, I recommend opening a ticket so we can investigate further.
