If your ATA is running skinny right now then I think it is not possible (because no callmanager in the picture).

But if you load your ATA with a SIP image then in the SIP proxy filed, you can specify the IP address of the other SIP ATA and then you should be able to call from one ATA to another.

I haven't tried that with the ATA, but done with the 7940 phones and it worked.

To get the dial-tone, you must configure a number for the ATA first. (UID)

To reset the ATA for factory defaults

Hope this would help.

you can use the g.729 codec that would nee approx. 20 kb per call with overhead included.
