You can use your office phone as your FAX number!
If someone wishes to send you a fax, have them call your office phone from the fax machine. When the call comes in, let it go to voice-mail or transfer the call there. When they hear your greeting, they can push their
send key, and your voice-mail will capture the fax.
If you have
Enabled Voice-Mail set up, the fax will be delivered as an attachment in an e-mail message to you!
