[cisco-voip] Phones not registering with 2960S switch.

[Joel Perez]

Can the subnet assigned to Vlan205 be reached by the CUCM gear? If they
unregister then they are probably loosing connectivity back to the cluster.
I have had misconfigurations where the vlans where mixed up. As long as all
the subnets were routable then the phones would still register.
