Is this handset identical to the handsets that come with the KX-TG7644M?

I bought mine to add to a KX-TG7641 system. It matched those handsets exactly and was simple to register into the network. It appears to be the same as the handsets used in the KX-TG7644M and I would not hesitate to try it.

I purchased this to go with the KX-TG7641 system and it was an exact match. Not sure the difference between the 7641 and the 7644M.

Yes, each handset has a headset jack. The Operating Instructions that came with the phone list the following headsets as "Additional/Replacement accessories": KX-TCA60, KX-TCA93, KX-TCA400, KX-TCA430. So I would think any of these would be compatible with this phone.

I'm not sure. But what I did was that I called Panasonic customer service and asked what handset will match the base, they give me the model number and I found it on Amazon.

The model I have looks like same as in picture. Every handset has its speakerphone.

I should add that, as far as I know, only handsets originally bought from T-Mobile support WiFi Calling (a.k.a. UMA).

No it does not. You want the KX-TS4300B which is the same phone with answering machine.

We regret to inform you this handset isn't compatible with the KX-TG6533. That system works with the KX-TGA651, KX-TGA401, KX-TGA750 and the KX-TGA652 handset.

If the handset for the KX-TG9541 has an input on it, I would say yes. The would be the deciding value.

Yes! It's exactly the same physical phone, just the programming is slightly different.

Yes, that is the exact same model phone and carrier I have. I've been using this set with that phone for several months without any problems.

Yes. The handsets are all identical. Any of them can function on the main base. The only function of the auxiliary bases is to charge the batteries.
1400928
Yes. Just make sure they're the same model. We have 1 "base" plus five additional stations. The handsets are all interchangeable.

I used this with my KX-TGA652 handset without any problem. I think it should work with your handset.

I purchased it as an extension formy model # KX-TGA931T and it works just fine. I think it is interchangeable with the other "900" series phones.
