The "VoIP server" could potentially be set to the IP of the other device. I'm not sure as it's been a long time since I've had to configure one of those Sipura-style ATAs. We use PAP2s for ATAs, and I haven't played around with the full range of settings.
One thing I do know is that there are a lot of settings in those ATAs, and my guess is that there is a way. That's not very helpful advice, I know, but I would tend to suspect that this can be done. Some things I can think that might be helpful: 1) Set up a port mirror on the switch between the devices, and use wireshark to capture the SIP signalling. That'll give you a MUCH clearer picture of what's going on in between the devices when they try to communicate 2) You probably won't be able to dial between the devices using a numeric extension. You'll need to use a full entity@address style URI. This can likely be set up in a speed dial for now. Since I haven't dug too deeply into your requirements (and haven't played with those partiular models in several years), I fear that any further advise would not be very useful. I'm fairly certain this can work, based on the following two things: 1) The fact that SIP is a peer-to-peer protocol, and 2) That the options on those SPA-style ATAs are impressive. Perhaps google for something like "hotline" or "intercome" "between SPA ATAs", or something along those lines. Another thing worth doing might be to get a config dump from both devices, grab the admin manual, and make sense out of the options. There should be a way to "dial without proxy/authentication", and there should be a way to dial a URI (probably using speed dial), and there should be a way to "accept unauthenticated calls". That's the sort of things I'd be looking for. That's all I've got.
