Ron, Here are some specific examples which I have run into regarding the connection of non-approved products behind PBXs.
In the UK the position is that if it has an analog interface it must be approved. You can use non-approved products behind PBXs but only if the interface is digital, i.e. could not be used on the PSTN. The Swiss take a slightly different approach saying that the product with an analog interface does not need an approval to be used behind a PBX if it's listed in the approval of the PBX. I assume that it would then have to carry some approval notice associated with the PBX. The Germans don't seem to care as long as you don't connect it to the PSTN. Hope that helps some. As in everything else with telco, each country's different.
