For any other dummies who may look at this thread trying to figure out what I was wondering about, here's what I discovered through experimentation. Telnet to the ATA and log in. Hit Cd to get to the dial plan section of the admin login. Hit "e", which will erase the current dial plan (you might wanna hit "p," which will display the current dial plan, and write it down for future reference, before erasing it). Hit "a" to add a dial plan. At the resulting prompt type *x.T and hit enter. Hit "a" again and at the resulting prompt type x.T and hit enter. Then hit "p" to look at the entries you just typed in to confirm they were enetered properly. If so, hit "w," which will save them. Hit "H" to go back to the main menu. There, type "Id" and the system will display the entire dial string, enclosed in parenthesis (the system does this, you don't need to enter any parentheses when you type the dial plan strings). The log out.
That gives you perhaps the most generic dial strings you can get on this device. Pretty much anything you dial gets passed to voxalot; you can fiddle with dial plans there to get better functionality. More functionality is possible on the ATA if you want to fiddle with the dial plan there; see the user's manual at
http://www.innomedia.com/manuals/SIP...nual_1.211.pdf for a little more information on forming dial strings.
But in any case, no need for entering things like VoIP_Digit_Map, the equals sign, quotation marks, or parentheses.
