Model el51203.....the person I am calling cannot hear me but

Customer Question

Model el51203.....the person I am calling cannot hear me but I can still hear them. I unplugged both charger bases, unplugged the phone thing from the wall, unplugged the phone batteries. Waited a few minutes. Attached everything after about 3 minutes. Did not fix the problem. Phones are only about 4 months old. Don't have my receipt or boxes anymore.
JA: How old is the phone?
Customer: About 4 months old.
JA: How long has this been going on? What troubleshooting have you tried?
Customer: 2 weeks. Have disconnected charger bases, the phone jack from the wall and removed batteries from both phones. Waited about 3 minutes and then reconnected everything. Tested phone and the other person still could not hear me.
JA: Anything else you want the phone expert to know before I connect you?
Customer: No

Hi, I'm Nathan.
Sorry to hear that you're having trouble, but I'll do my best to help you. Please give me a few moments to review your details here.

Expert:  Nathan replied 6 months ago.

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?

Customer: replied 6 months ago.
I have two phones on the same system. It is happening with other phones or a fax. I subscribe to Comcast. No dsl service.

Okay can you start by unplugging power to your comcast modem/gateway, let it sit unplugged for 5 minutes, then replug, and give it about 5 more minutes to start back up, then test the ATT phones again and let me know the results.

Didn't work

Thank you for trying,

at this point it is still not possible from a diagnostic perspective to know if it is a comcast problem or an ATT problem. Both are very common, the only way to isolate this would be to test another phone, preferably just a basic corded or wall phone, on the line. Could you dig an old one out of storage, or borrow one from a neighbor for a few minutes to test?
