Sometimes callers can't hear me. I have adjusted my band width several times, my cable modem, and router are all new. This is becoming the last straw.
Power off the Ooma device for one hour. Then repower the Ooma Device and test.
If that doesn't work, do the following two steps:
Try connecting your Ooma device Modem-Router-Ooma. When using this connection, nothing is connected to the Ooma Home port, except temporarily a computer, with a network cable, when making adjustments to Ooma Setup. Set your Ooma Setup Quality of Service Upstream and Downstream Internet Speeds settings to Zero.
Access Ooma Setup and change MAC address from Automatic to Use Built In. Reboot the Ooma device, and test.
