That's okay, either way, I never thought about doing that for TEHO, so his question may have helped me in my planning on the lab! Its all good!

So are you looking at like a TEHO solution. If the TEHO gateway is down, then send to local so the call goes through From: c george [mailto:cisco...@hotmail.com] Sent: Wednesday, August 26, 2009 11:12 AM To: Steve Sarrick; bobwmcg...@verizon.net; ccie_voice@onlinestudylist.com Subject: RE: [OSL | CCIE_Voice] Local route group question i beleive it is the other way around. The local group would be the 2nd choice not the 1st. The primary route group (gw) would the 1st in the list.

The Standard Local Route Group would be set first in your Route List and then a secondary option would be set in the route list. In the event your Standard Local Device fails, the calls based on that route pattern would use the next available option.

So if all pstn connectivity is down on a device pools local route group can calls be re-routed out another gateway? ________________________________ From: ccie_voice-boun...@onlinestudylist.com [mailto:ccie_voice-boun...@onlinestudylist.com] On Behalf Of Mark Snow Sent: Wednesday, August 26, 2009 10:06 AM To: SYED HUSSAIN Cc: ccie_voice@onlinestudylist.com Subject: Re: [OSL | CCIE_Voice] DHCP snooping limit rate for Voice traffic... As noted in the CUCM SRND here: http://www.cisco.com/en/US/docs/voice_ip_comm/cucm/srnd/7x/security.html #wp1045687 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).
