thanks
so there are 2 obi numbers on each device
one is obi # and is 290xxxxxx
it has a headphone symbol, called sp 1, and an orange head indicating offline
the other,has an obi device-like symbol, called sp2, has a green symbol indicating online and is 200xxxxxx (it is also referred to as the obi gateway)
what is the difference--- can either be used?
