Existing Cisco 1750-4v has one WIC-1T and 1x VIC-FXO, 8MB Flash and 32DRAM.
But I need to extend the voice to 2 VIC-2E/M, hence I need to remove exisitng VIC-FXO.
I have one questions, if I need to add 2 VIC-2E/M (remove existing VIC-FXO), do I need to upgrade DRAM. Flash ram, I think it is ok as IOS is not required to change (now is IP Voice).
Do Cisco has tools to check this kind of upgrade ? I can't use Configuration agent to treat as new configuration as Cisco 1750 is EOL.
