From my testing I found that you have to dial the 10 digit phone number for this to work. 7 digit dialing does not work. Also, I would like to suggest the ATA be setup to give you the second dial tone like you did with *67

The short call I made to test it recorded fine and the audio was clear. File size was 533 KB on a call less than 2 minutes. Overall I think its a very nice additional feature. Thanks guys!
