Ooma Dropped Calls - Related to 2Wire 2701HG-B?

Post by bmccollum » Thu Sep 23, 2010 10:58 am

My parents have an integrated wireless modem / dsl router... the AT&T-provided 2wire 2701HG-B.

They're having a huge voice lag issue when using their Ooma Telo device connected to the integrated modem/router.

Additionally, they're experiencing various glitches and hiccups with the voice transmission during a call.

Lastly, they're experiencing frequent issues where they're talking on the phone and all of a sudden, the line just goes dead in the middle of the conversation and they're taken back to the Ooma dial-tone.

Highly frustrating!

They have AT&T Fast Access DSL 6.0 Internet service.

The AT&T-provided 2wire 2701HG-B unit is very poorly rated/reviewed all over the Internet, with the vast majority of the people that have used that unit being highly-disappointed and having lots of connection droppage issues and so forth w/the 2wire unit.

We have the Ooma Telo in our house and absolutely love it! No problems. We have Cable Modem broadband and the Ooma Telo unit is connected literally as far down the chain of connection of equipment as possible (cable modem > wireless router > 8-port switch > Ooma Telo), so *we* of all people should have a cruddy experience, but we have no voice lag or anything else... no problems at all...

Just trying to get my parents' issues identified and resolved so they can make calls via their Ooma Telo and hopefully be as pleased with it as our household is.

Thanks for any recommendations or suggestions...

Ooma (or any voip phone) need more than just speed (bandwidth.) The problems at your parent internet may be jitter and/or packet lost. You need to do a speed test at


then post the result here. (Note copy all at the "Text" tab)

The problem could be the modem, or it could be the signal itself. After the speed test, with some concrete number you can call ATT and ask them to do a line test. If the test ok, then you might try a new modem.

I had a similar issue a while back and fixed it with port forwarding on the 2WIRE system. I was asked how I fixed it so many times that I posted a tutorial on it. Let me know if this helps:
