Network design which Cisco router should be buy??

Currently I have a Cisco 2921 router at my data center running BGP with dual GigE Internet connections. We are providing a hosted Voice over IP solution for about 2,000 IP phones. The Cisco CPU runs at about 90% during peek hours of the day which is forcing us to upgrade. We were thinking of upgrading to the Cisco 3945e but feel we might max this router out in another 12 to 18 months. The CPU and packets per second are important to us since QoS needs to be maintained for voice quality.

We are looking for suggestions.

Thanks

what services is the 2921 router handling, routing only? NAT, Voice gateway, VPN, etc?

Have a look at the table in

Based on your required bandwidth / packet rates you should be able to choose which range to go for

7600 would be very good, though, if you don't wan't to go that far yet and you still want to get a fair amount of service time for your aquisition, a 7200 with an NSE100 should be good enough. :)

Our setup is pretty basic. NAT, BGP, site to site VPN, Currently we only have the 1 router which is a single point of failure on our network. We cannot afford downtime so I need to build a redundant solution which of course fits within our budget. We have 2 GigE fiber connections with 2 ISP's. I would like to purchase 2 routers and peer each with an ISP and still run BGP.
