Thanks everyone's input and suggestions and Norm from L3 support. After isolated the problem of my modem/router (Netgear), I checked the router setup and found nothing special. I went to Netgear home site and looked up the Downloads. I found the following message (in red). I downloaded the new version of the firmware. My "no incoming sound" problem is fixed.
I then removed Ooma from DMZ, Ports Forwarding for the nine sets of suggested Ooma ports and static IP address in the Ooma box. I'm glad that I don't even have to disable firewall or SIP which will make me so uncomfortable even for a very short period of time. In between each removal, I repowered modem/router and Ooma one by one in the right order. The Ooma remains functional in each time. In conclusion, my problem is the modem/router. Once I downloaded the new version of the firmware, everything is working properly.
DG834v4/DG834Gv4 Firmware Version 5.03.16 (for North America)
This firmware is only for DG834v4 or DG834Gv4. Do not use on any other DG834 product!
For users in North America only.
New Features & Bug Fixes:
Fixed a problem where inbound audio when using VoIP phones could be garbled.
Added support for NAT loopback.
Fixed a performance problem with regard to PS3 on-line gaming.
Your unit ran into bug 9681 which is a bug that crops up on some networks. The solution is to power cycle the box. That will work most of the time. If not then call support and they will escalate the issue.Try the press play on the ooma to access my voice mail, nothing.
Having the same issue. Power cycle does not resolve and don't expect it to because the failover number does not work.Tom B wrote:This inbound problem is separate from what I commented on earlier. Since your power cycle that problem has not reappeared. I see a number of successful inbound calls today, so is the problem intermittent or only for calls from certain numbers?
Have sent my clients with Ooma a status update. They all report the same issue.
L2 CS said the problem is Ontario wide.
Ooma to Ooma works.
Inbound to my US number works
Inbound to my Canadian number worked temporarily, but now fails again (three short beeps when calling from my cell phone, then disconnect)
All outbound calls work.
Just tested 3:14pm EST. Problem persists.
