My guess is if you have experienced them you may not remember much about it - unless you are Barney Miller.

Good job!

I think someone was having problems with his professional grade internet.

Do you have Cable Modem or DSL? Or do you pay for your own T1 line in your house? If you run the tests from the links I suggested and post your response, especially jitter and QoS we may be able to help you more.

How do you have your network setup.

Recommended setup is Cable/dsl modem - Ooma- Router - computers

If you have modem-router-Ooma and your router does not allow you to configure QoS then that may be your problem.
Either your router, or the Telo needs to be able to handle QoS to give you a good sounding phone conversation.

What version firmware do you have on your Telo? version 35452 is the latest.

Depending on how you have your system setup, try going to and if that comes up click on status and towards the top, it should show you the version. If that does not work try entering in to get to the setup.

Wow, thats odd, there def is a problem somewhere, whether you have a bum telo base or something.

What I would recommend doing next, is disconnected the Telo from your setup completely and re-run the tests, If you do not have the Telo connected and you dont have an issue with packet loss, than the problem probably is with the Telo, if you still have that high of a packet loss, than your problem lies elsewhere.

Do you have cable or dsl?

My suggestion would be to place the OOMA device before your cisco router. I teach cisco switches and routers to postal ET's and know that by default their security limits can cause problems with VoIP devices unless they are configured with QoS and ip_helper statements set correctly. You can at least test this my placing the OOMA device before the router. In other words cable/dsl modem ---> OOMA Device ----> Router if this fixes your problems then i would suggest either leaving it that way or putting it back the way you had it and setting QoS and adding either IP_helper statements or setting up a DMZ port if your router is able to do this. I don't know what model cisco router you have or i could give you those statements that are needed. Mostly its just ACL statements but they have to be in the right order.

The OOMA device has to be able to access these ports or it will not work correctly. ... vice-ports

The 100% loss is something I missed in my ranting - normally I don't see this. I'll test again.

I have QOS configured on my Cisco using NBAR for RTP traffic in a priority queue - so that's all set up right.

I'm suspecting IPS at this point. That said, I've turned off everything before (except NAT) and still had issues.
