For those of you working with Fax of IP, an interesting book called "Fax, Modem, and Text for IP Telephony" was recently published by Cisco Press. This book covers both T30 and T38 basics, as well as much more. It has very positive reviews on Amazon. Check it out!

Shifting gears...

Need to see if a fax works, but don't having anyone who can send you a fax? Check out the free service from HP that allows you to send a fax and then using inbound fax number returns a fax to you within 5 minutes. Pretty cool!
