## HTTP/HTTPS Servers with Default Ports 411/81/80

Both 9600 Series IP Telephones and 4600 Series IP Telephones support HTTP, and by default, use the following port assignments:

- Port 411 for TLS download of configuration files from the IP addresses listed in the system parameter TLSSRVR.
- If configuration file download succeeds, the telephones then attempt to obtain firmware files from Port 81 from the IP addresses listed in the system parameter HTTPSRVR.
- If the attempt to get firmware files fails, the telephones then use Port 80.
- If the system parameter TLSSRVR is null, Port 80 is used with the IP addresses listed in the system parameter HTTPSRVR for all file downloads.

The HTTP server function delivers configuration and firmware files to IP telephones. By default, these settings are stored in the HTTPdata directory of the application hierarchy:

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

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

A secure download option is also available with an HTTPS server – which uses these defaults instead:

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

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

For secure operation, the File Server application supports TLS and specifically, the authenticate only mode used by Avaya IP Telephones. In addition, the older SSLV3 and SSLV2 protocols are supported but not enabled by default.
