I'm looking to get some Cisco Routers for our outer offices. I've settled in on the 1811 unit.
What exactly is the Flash memory and why would I need or want to upgrade that?
What is the RAM used for in the router and why would I need or want to upgrade that?
This stems from the horrendous cost of the Flash and RAM upgrades for the 1811. I'm just wondering whether or not I would need to worry about it. Even if I don't get the upgrades now, how will I know in the future if I need them?
I do plan to get the Advanced IP Services IOS for the additional features.
We are currently using SonicWALL units in our offices but are having trouble with them and VoIP. I would like to get one Cisco and get it configured and deployed to see if that resolves our issues.
The 1811 with the built-in modem seems to be the closest match to the SonicWALL TZ 170 SP with Enhanced OS.
