I'm designing for a new office and am looking for help with which Cisco gear to order. It has to be Cisco and I just need help on the router and firewall stuff.
The new office will have two ISDN-PRI T1s. One for voice, one for data. The firewall won't be doing any VPN stuff. Just straight filtering and NAT.
I am looking at a 2811 ISR with two VWIC2-1MFT-T1/E1 interface modules. We are hoping to go to SIP in the future so I chose these for flexibility. Also looking at an ASA 5510. Will these do the trick or is that overkill?
