About the Console Download Function
You can use console download, which is a ROM monitor function, to download either a software image
or a configuration file over the voice gateway console port. After download, the file is either saved to the
mini-flash memory module or to main memory for execution (image files only).

Note
If you are using a PC to download a Cisco IOS image over the voice gateway console port at
115,200 bps, ensure that the PC serial port is using a 16550 universal asynchronous transmitter/receiver
(UART). If the PC serial port is not using a 16550 UART, we recommend using a speed of 38,400 bps
or less when downloading a Cisco IOS image over the console port.
