I have a basic set up - MX67, MS225-24P, and a single MR33 at a small office. There no vlans.
I was playing with some Yealink VoIP phones today, and setting up the group paging feature. The phones are wired in, so the AP is not in play.
It was working fine, until it just stopped.
I tried several IP addresses (all in the multicast range). I rebooted everything. I spent almost 3 hours on the phone with the phone vendor.
IGMP snooping & Flood unknown multicast traffic are both enabled.
The phones were reset to factory settings several times.
Nothing I tried would make it work again.
Any ideas on how to either test it or get it working again?
