My answering

machine won’t

pick up calls

• Set your answering machine settings to

pick up calls before network voicemail,

which is approximately four (4) rings.

• Or, you can have network voicemail

removed from your account by calling

AT&T Customer Care. Dial 611 from your

connected phone or 800-901-9878.
