Hello everyone, I'm fairly new to this, I've tried a couple times but It didn't go very well.

So I'm wanting to make a project with my ATA (a Linksys pap2t, not much but it's enough for what I need) and before I buy the devices I'm missing, I'd want to test the direct IP call or fax between my ATA and another one that's anywhere else, is there a way I can do that and make sure it works the way I want it to before setting everything up?
