I am used to large scale fax setup, so I am more familiar with DIDs assigned to FAX and then use IAXmodem to Hylafax. Sounds like bigtime overkill for your use. You could look at www.trustfax.com (no affiliation but a happy customer), better service than www.efax.com as far as I am concerned and better pricing. My faxing requirements are very low though. Most customers that insist of dual use POTS lines invariably complain about the "delay", which I have to explain, especially if they have caller ID too. -- Thanks, Steve Totaro +18887771888 (Toll Free) +12409381212 (Cell) +12024369784 (Skype)
