Good morning all,
We have recently ran into major issues using Yealink phones, particularly T54W and T57W. Calls are broken and dropping. We have determined the ISP and internal networking is not the issue due to the fact that these issues are not specific to one customer. Does anyone have experience these products they would like to share the do's and don't's with the Yealink platform? We have been making small adjustment to the voice settings of the hardware but are not having any luck. We are not showing any packet loss between customer and cloud. We are using Unifi switches and Mikrotik RB2011 firewall. We also head similar results using a SonicWALL. VOIP traffic is all travels though the Mikrotik and LAN uses the Sonic wall. Quality issues are becoming more and more frequent but are still very random. Yealink support is looking into this but not moving fast enough. Thank you in advance for any information you can share. I am open to any suggestions at this point. If there is a better suited platform to ask this question please let me know. I figured I would start with the smartest group of people I know.
