I have two Ooma Telo’s and have had nothing but issues with them. Both are on the same network - One in my home and one in my shop (for business). Sometimes they work, but most of the time they don’t. When they don’t work, the light is blue, but I cannot call in or out. When I call in, it never rings, although it does ring the Ooma app. When I call out, there’s a long delay, then a fast busy - I can call out just fine on the Ooma app.
At first, I had them hooked up via the wireless adapter. I’ve eliminated that and they are now wired - No change. I’ve even changed my internet service recently and it’s still doing the same thing. This included changing out the router. My bandwidth is more than enough (100 down/25 up), with latency under 100ms and jitter under 30ms.
I can’t for the life of me figure out what’s going on. Any ideas?
