## TFTP Server with Default Port 69

The TFTP server function delivers configuration and firmware files to 4600 Series IP Telephones. These settings and files are normally stored in the TFTPdata directory of the application hierarchy by default:

For Linux: /opt/ecs/mvuser/MV_IPTel/data/TFTPdata

For Windows: c:/Program Files/Avaya/MV_IPTel/data/TFTPdata

Devices can access this directory with the TFTP protocol to retrieve the appropriate files.

NOTE: TFTP is exactly that – trivial and not robust. See Improving TFTP Reliability on page 38 for options to improve download reliability by limiting connected clients by number or IP address and to allow notional “timed sessions.”
