Cisco router redundancy
Hi,
We have a Cisco 2851 router that is configured as the voice gateway for the Cisco phone system.
a. Can I get another 2851 (another another router with the required hardware) and configure VRRP or HSRP? Will either of these protocols work for a PRI (not internet) router?
Thanks!

Yes.

OK...how do I connect the (one) PRI I have from my phone provider to both routers to allow for failover? Can I even use GLBP or is it between HSRP and VRRP? Some more information would be helpful...
Oh...
No, you can't do that. I thought each router had it's own circuit.
You could have have the service provisioned into two separate fractional services with 12 timeslots going to each router.
But you can't terminate a PRI to two routers.

But if I have "two separate fractional services with 12 timeslots going to each router" - I cannot use HSRP or VRRP since they are active/passive technologies?
