Hi, I'm Nathan.
Sorry to hear that you're having trouble with this but I'll do my best to help you.

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?
