Iirc Motorola has a solution that allows in-operation linux kernel
upgrades. No idea how they pulled that magic off (and if it actually
works). At VON IBM was going to demo a blade based Asterisk solution
that has auto-failover of calls so maybe that could also be used to
upgrade software. Don't have more info about this IBM solution. If you
have a DS3 or OC3 worth of TDM calls then it probably makes sense to use
a carrier-class box.
