[cisco-voip] CUCM 7.1 Change Default Gateway and Subnetmask

[Mike King]

Someone else correct me if I'm wrong,

But think that is considered a "bad idea."
http://www.cisco.com/en/US/docs/voice_ip_comm/cucm/rel_notes/6_1_4/cucm-rel_note-614.html#wp871286

You would hit the hard limit of 1024 arp table entries.

This limitation exists all the way up to 8.5.1 (I could only
find Cisco documentation referencing 6.1 quickly however)
