We don't aggregate devices in chan_sip - that's done in the pbx core. You would then have aggregation twice which is not a good thing, like forking twice. If I want to implement a device state proxy that says "if one phone is busy, all is busy" I would have to implement that twice, once in the core and once in the sip channel driver. That's no good.

I think this is too large a step for the first version of the new channel driver as it will affect the PBX core too.
