I want to use feature set "VOICE IP TO IP VOICE GATEWAY" on our router 3745. Do you know which IOS version i should use that requires less DRAM and flash. My router has only 128 DRAM and 64MB flash.
Hi, to know memory requirements for any IOS feature set, please use "feature navigator" on CCO. I think it requires customer-level acces (that you have bough a service contract).
I have use "feature nagivator" and it just give the IOS c3745-js2-mz.12.3-14.T7 which require 256MB DRAM and 64MB flash. Our router only has 128MB DRAM and 64MB flash. We don't want to upgrade DRAM...
Consequently you can't upgrade IOS. Beside, there are licensing issues that you should consider or discuss with a sales office before upgrading from one feature set to another.
