[cisco-voip] IOS MGCP question

[Kevin Thorngren]

Hi Ed,

As long as you have enough main memory you can use the boot system 
command and boot the image from a TFTP server.  This would be fine for 
a lab environment but might not be ideal for production.  If a flash 
upgrade for the VG200 is still available you might be able to get away 
with the TFTP workaround for a short period.
