I've been struggling with this question and haven't been able to find a clear answer; can a local route group support call redundancy? So if all pstn connectivity is down on a device pools local route group can calls be re-routed out another gateway?

As noted in the CUCM SRND here: http://www.cisco.com/en/US/docs/voice_ip_comm/cucm/srnd/7x/security.html#wp1 045687 Cisco doesn't set a "best practices" rule. Instead they say (and rightfully so) that it depends on your Security Policy. You would really have to have more information such as: - How many phones on the DHCP Subnet? - How often do they renew their leases? - Model of the switch? All in all, as with most things in security that you wish to limit, you really need to establish a baseline for your own DHCP Voice traffic, and then create a limit slightly higher than what is "normal" DHCP traffic (in PPS).
