The phone is under warranty if under 1-year old, according to the product manual. You need to contact AT&T for service or replacement. The manual lists the following contacts: http://www.telephones.att.com or call 1-800-222-3111 (in the U.S.), or 1-866-288-4268 (in Canada)

That I'm not sure on. I will say if you don't already own these phones I wouldn't buy them. I had a lot of trouble with my set. Sorry I couldn't help more on the model number.

You have to have a base to use the accessory hand sets. My base is a vtec cs6619. I put the new handset in the base and within a few seconds it beeped and was registered. It worked fine for me.

Unplug everything, make sure everything is plugged in again, check the battery in the phone, and everything should work. If not, send it back and get another phone.

change the date time on the phone to 30 June 2013. Then download the app catalog. Reset to today's date and you'l be fine. It has to do with when HP's security certificate was updated for these phones

I did the same thing, ordered 2 phones that didn't work--went on the internet and found the phones that matched--they will tell you !! which ones work and the ones that won't

I'm sorry you have had that problem. We had one handset stop working completely, and all of the others only work, if we stand in a particular spot in our home! I rated this set 1 star, and I am ever so sorry I wasted the money I did on it. I am currently in the market for a new set (NOT A PANASONIC!!!), and will bite the bullet on this one. Shame, as I had high hopes for it....

I have had a lot if issues with ours and it is less than a year old. They have traded us parts to replace things. I am sure if you go through their website they will allow you to buy a new handset. I will say their customer service is horrible if you try call, it is better if you go through their website. Good luck.

I have a blu tel and it works very well. I suggest reviewing the placement of the SIM card. You can try placing the card in another PhoneSet to see if it works. You should also check the settings. luck

You might have to factory reset the phone: http://www.youtube.com/watch?v=e60kvh12EC8

I had the exact same issue. I got other handsets and they work just fine. Ooma handsets are horrible.

I just experienced the same thing. I got the phone yesterday, plugged in a SIM I already had from England and that worked so I went to AT&T;, got a SIM and put it in. It didn't work but the sim worked in other phones and other sims (eg T Mobile) worked in this phone. Now, a couple of hours later, it's working. Go figure.
