[cisco-voip] CME & Redunancy?

[Sean Watkins]

Yah I saw this, but where do I configure CCME to use the standby address?
There is the source address option under telephony-services - maybe I'll
give that a whirl.

I don't know the exact answer for this but it looks like HSRP is the way to
go from a quick scan of CCO.

IP-HSRP testing
Configure HSRP between the two Cisco 3825 routers and the two Cisco 3845
routers. IP phones should register with the virtual HSRP IP address, which
is tied to the primary voice routers. IP phones must reregister with the
backup router.
---	
Verify IP phones will reregister with the Cisco CME on the backup router
after the master HSRP router goes down. Also verify PSTN trunks failover.
---	
The IP phones were registered to the primary Cisco CME router and failed
over to the backup router. The failure was simulated by pulling the electric
plug on the primary router. 
---

To configure HSRP put something similar to this on each router that is to
participate...
ROUTER#1
interface FastEthernet0/0.88
 description Phone Network
 encapsulation dot1Q 88
 ip address 192.168.88.2 255.255.255.0
 standby 88 ip 192.168.88.1
 standby 88 priority 110 preempt
 service-policy output L3-to-L2-SubInt

ROUTER#2
interface FastEthernet0/0.88
 description Phone Network
 encapsulation dot1Q 88
 ip address 192.168.88.3 255.255.255.0
 standby 88 ip 192.168.88.1
 standby 88 preempt
 service-policy output L3-to-L2-SubInt

The default priority is 100. The higher priority will own the route.
HSRP takes up to 10 seconds to fail over.
You can type show standby to see who owns the route and the routers that are
sharing the route...

Good luck :)

Hi,

Is there any way to setup CME for some redunancy using HSRP etc? I have
found some references on CCO, but nothing in any docs on setting it up.
