yes it can but on the local group when added to that list you will specify to
add\prepend a 1

Thanks for the answers; this is what I’m trying to figure out:
(Local call Massachusetts) Route pattern 8.617xxxxxxx
Device pool A --à Local route group A ---à gateway A
(Situation) Gateway A goes down or the PRI goes down.
Can a phone in Device pool A re-route its outbound local call route out Gateway
B’s (California) PRI Pre-pending a 1

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!

Okay, I’ll bite…
So are you looking at like a TEHO solution. If the TEHO gateway is down, then
send to local so the call goes through

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.

I’m not the expert in this, but if I understand what you are asking….
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.

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?

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).
