5g internet and Ooma telephone
Anyone having any trouble with the Ooma telo going offline and back online constantly throughout the day? Mine will show the blue ready/online symbol on the device but if i check the dashboard status...
The funny thing is my OOMA goes offline a lot and after speaking to T-Mobile IT they explained that voip and Cellular Internet it's not a good mix, but i found out later T-mobile offers OOMA themselves. not sure if the issue is with OOMA, or T-mobile.
I tried these as well - it helped some, but not fully:
Ooma Telo device needs the following ports and protocols to be open in your router to ensure trouble-free communication:
Remote: (Outgoing Firewall Rules)
UDP/TCP 53
UDP/TCP 1194
UDP/TCP 1294
UDP 67
UDP 123
UDP 3480
UDP 10,000 to 20,000
Local: (Incoming Firewall Rules)
UDP 49,000 to 20,000
Make sure that the above required ports are open. In addition, we also recommend that the router feature called UPnP is ENABLED and SIP ALG is DISABLED.
