Hello & Welcome to Just Answer,
Sorry to hear of any issue you are having with your phone and the talk button.
To help you with this issue, may I ask:1) The AGE of this system (approximate is fine)?2) Do you have ANY experience taking apart small electronics like this?
3) Can you tell me what other brand of phone you tried?
I see it has been a few days and I just wanted to follow up to see if you have any more questions concerning this issue or if the issue was resolved.
I only ask because very often what it takes to get these older unit working is to disassemble them, clean the contacts, and in some cases replace the key pad(s).
Here is an example video that shows how this can be done
- This video may not match your handset exactly, but the concept is the same.
- Replacement keypads can be found mostly online, as places like eBay.
I look forward to any further questions or results that you may have.
Thanks, ***** *****--. .-(im)
