My VOIP Phone went offline and I have checked the connections and they seem to be fine. ISP is Cell C and the internet is working.
The hand set is a Yealink W56H with a W60B Base station.
Can you please assist.
I've answered your question on the private ticket you created.
Please try changing the local port on the base station to 5090. Sometimes the local port the phone uses on your internet router gets congested and doesn't allow traffic to move through it. Another way to combat this issue is to switch router off and wait for 20 seconds and then restart.
