Hello & Welcome to Just Answer,
I'm Greg and will do my best to assist you today.
Sorry I didn't see your question earlier and to hear of any issue you are having with your phones.
To help you with this issue, may I ask:
1) The FULL Model Number of the phone system you are working with? If this is a cordless system, that model should be printed on a sticker on the bottom or back of the MAIN base.
2) What phone service provider (phone company) you have for this phone line?
3) When you typed "It keeps call #74 to set" what does that refer to.
Sorry - as stated above, I simply did not SEE your question earlier.
ALSO - We experts are "users" of this site - just like you - and have no access to ANY of your private information or account. But YOU should be able to manage your account by clicking the "my account" link on your side of this system.
If you have ANY concerns about your account or site operation, You can contact the Customer Service department at the following page:http://ww2.justanswer.com/help
Please let me know if you have any more questions - about your phone system - now or in the future.
Take Care, Greg A.
