Electronic Fax and Message service

The best I found was
Maxemail

For $24 I got a phone number in Chicago with fax and voicemail for a year. You can personalise the greeting and the fax header.
Support reply quickly and at weekends.
Faxes are sent as pdf and voicemail as wav and you can email files to fax numbers
You can include a few email addresses so you can share the account. Plus you can have all messages saved for a year, (costs extra).
In short it's good.
