RE: 3CX Cloud 12, Yealink T46g, and Audio Problems
The direction of the audio loss tells a lot about where the problem is. Is it incoming our outgoing audio? Outgoing audio loss would mean that traffic from you isn't reaching its destination (or is getting there way too late). Incoming audio loss would mean the audio isn't getting to you in a timely manner (or at all).

Outgoing audio loss is easier to control. You can prioritize the packets on your own network so that voice gets first dibs. Usually this is done with DSCP on the internal network, or with 802.1p and vlans (usually with DSCP conversion for layer 3 devices).

Incoming audio issues are often out of your control. An internet connection with inconsistent latency and/or loss from your provider can cause many problems for VoIP. Your firewall can also cause problems through UDP timeout issues or NAT issues.
