Hi, I'm Nathan.Sorry to hear that you're having trouble with this but I'll do my best to help you.
My apologies, I had sent some follow up questions to you but it looks like they didn't go through:
Can you tell me a bit more about the problem please:1) If you have multiple handsets (within the same system), does this happen with all of them? 2) Are there other phones or even a fax, outside of this system but on the same line? If so are they working properly?3) Is this a landline from the local phone/cable company, or a VOIP service (vonage/magicjack/etc)?4) Do you have dsl service on the same line? 5) Full model of the phone(s) (printed on sticker on the base usually)
Great thank you for the information, so that is an iphone 4, correct?
If you put it in speakerphone mode, while on a call, can you hear any better on that?
Okay that usually points to a hardware problem,
one thing to try though is, while actually on a call, pressing the volume up button (at the top left edge of the phone) repeatedly , and see if that increases it.If not, it is a faulty speaker, and the phone would need to be repaired/replaced.
How long have you had this phone and do you have an applecare or att service plan on it?
You're very welcome, Wanda.
There was a software update that went out last night, so it is possible the reset that happened during the update process resolved it.
If you have any other questions, just let me know. Otherwise, please take a moment to rate my service as this is the only way I am credited for my time. Hopefully I have earned 5 Stars but if not please let me know what I can do to ensure you are satisfied. I also invite you to contact me directly with any future support needs at http://bit.ly/1QwLxGh and ask for Nathan.
Thank you, ***** ***** a nice day,
