Cordless phones - different brand handsets?

Can I join two different brand handsets? We already have AT%26T (5.8 ghz) base and 3 handsets. We won in a raffle Uniden base + 2 handsets. Can we join the Uniden handsets to our AT%26T base? I know that there%26#39;s a process to register handsets to the base. I don%26#39;t want to open (and break the seals on)the box if it%26#39;s not going to work.

Answers:

It%26#39;s unlikely that different brands of handsets will communicate with off-brand bases. Otherwise we would all be picking up each others conversations throughout the neighbourhood.

Even though the phones may be on the same frequency band (eg: 5.8 ghz) there are still differences that are proprietary to each manufacturer that will prevent the phones from working together.

That doesn%26#39;t mean that you can%26#39;t use both cordless systems on the same line though. You can still have the AT%26T base connected to one phone jack in the house, %26 have the Uniden base connected to another jack. Then each of the cordless systems will operate on the same line for the same reasons that two wired extension phones would. I%26#39;ve never heard of it being done (the instructions and registering would be different on the phones ... even phones from the same company are not always compatible)

... why not just set up the new phones if you need them ... is this a matter of being able to use handset to handset calling. Because I can%26#39;t think of any other benefit of making them work together. Its not going to work...different phone manufacturers use different digital signatures. The two cannot communicate with one another. However, i would point out that uniden is generally the more reliable company when it comes to phone manufacturing. AT%26T pays Vtech to make and distribute their phones. The standard right now is 5.8GHz digital, however they recently came out with the DECT 6.0 which is an encrypted signal, meaning only professional hackers could listen in to your calls (or a hardwired tap) LOL no, you cant use ATT and Uniden together!
