GLBP works by answering ARP requests. If you were sending all of your calls out from a single CUCM subscriber for example, that one subscriber will have the same ARP entry and all outgoing calls will go to the same gateway.
It will work, but I don't think you'll find it to be an efficient load balancing mechanism.
GLBP was designed for first hop redundancy for a subnet of hosts, and I don't think this particular application of GLBP will work well for call load balancing. The idea is that with enough hosts, and by round robining the ARP requests, you can load balance.
