We are currently considering spec'ing a job for a customer that has a requirement for some redundancy in their phone/data system. Currently, we're looking to spec a UC560 with 39 handsets, a couple of wireless handsets, probably a WLC526 and a some LWAPs. The latter will obviously depend on availability.
I would like to build this system with full redundancy if possible. Ideally, we would include 2 UC560s so that if one somehow went down, the second would provide failover call and data routing. Is this possible?
