Level 3 escalation now supposedly.
Telo Handset using Telo base can dial anything I've tried now!
Call quality seems good, but I am a little concerned about the distance it can go - much better now, though, that it can call any area code/number, etc.
Now I can't wait to get my other two Handsets working and try out the full system!
Anyone from ooma support listening? CS-20192
When I could get to 800 numbers only and inbound worked I realized I did not have the AT&T Uverse Residential Gateway set to have the Ooma in the DMZ. In my network configuration I have the AT&T unit setup as going to the Ooma's modem port and then the rest of the network behind the Ooma's network port - basically making the Ooma the firewall and router.
I was waiting on support to address the ticket and made this change - I can't honestly say 100% that this isn't what really fixed the issue. At some point after making this change my wife told me she had called a number and it worked and she liked the new setup - so I just thought Ooma had solved it, but it may be the moving of the Ooma to essentially direct Internet access that did it.
Hope that helps - if you don't have the Ooma directly on the cable modem or DSL modem, maybe that will do it for you - just make sure you set the QoS to about 80% of your full speed average on upload - for example, if you have a 1.5MBPs uplink, set QoS to 1300 in the Ooma. Otherwise you will be unhappy with the Telo speed slowing down your network.
