1)The phones registered but when making a call there is no audio on the call once answered . If base is rebooted then calls are fine again , this happens randomly.
2) In some cases if I call the phone I get ringback on calling side and the phone does not even ring at all , yet it will be registered also happens randomly to resolve I also have to reboot the base and sometimes have to give it a new IP for it to work.

This is being experienced at 2 different sites both with Base firmware 77.85.0.20 and handset firmware 61.85.0.20. The one site the phones register directly to the provider and on the other they are behind a PBX . There are ither Yealink IP desk phones within these sites and they dont have any issues only the w60s are experiencing this problem.

Hi,

Reading the first part of your post (Q1 and Q2) I would almost say you have a problem with the router closing ports over time due to traffic safety.

What you can try is to enable the STUN feature of the base station so that the ports are not closed.

By rebooting the base station or by giving it a different IP address, the base station opens the correct ports again so that you can make and receive calls.

Hi complex1 , I am a bit limited on networking if I share a pcap will you be able to see this and confirm ?
