Hello, I am seeing some intermittent errors with Yealink phones.
We have a PBX with a ring group of 4 extensions.
When an inbound call comes in, a user answers but the other phones continue you to ring for a further 3-4 seconds.
I have looked on the server, and I can see that the server is sending no options packet back to the router but the phone logs it's self don't really show anything.

Attached is the phone logs of the phone that continued to ring.
Has anyone got any experience of this problem before? I have had reports of this happening on Snom phones but I am yet to see evidence of this. Any input here would be great.
