Hello Shirley & Welcome to Just Answer,
Sorry I didn't see your question earlier and to hear of any issue you are having with your phones.
If you still need help, may I ask:
1) How many TOTAL cordless handsets do you have with this system?
1a) If more than one cordless handset, do ALL cordless handsets have low volume to you?
I only ask so that we can know if this is an issue with only one handset or not.
P.S. I may be able to call you - if that is what you would like. That would be an additional service (and fee) here, but just let me know if you would like that method of communication.
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 look forward to any further questions or results that you may have.
Thanks, ***** *****--. .-(im)
