We have a number of stations, some of them in the same building on a single ethernet switch, and some of them in another building somewhere else in the world but with internet or intranet connections to that switch.
These stations need to be linked with an intercom, using external hardware. This should act like a party line, where one unit can press a talk button and be heard on all the other units.
Selective calling features or multiple channels would be nice, but not essental. There will be fewer than ten total units in place.
Does anyone have any suggestion for a device that does this as a simple standalone device, preferably with minimum configuration? I know Telex makes some VOIP modules which can be integrated with their intercom frames, but they all seem to require a central switch.
