TFTP (Trivial File Transfer Protocol) server
A TFTP server is required in the system to distribute software to the
handsets. It may be on a different subnet than the APs and/or
handsets.
SIP TFTP server
The SIP TFTP server is required in the system to deliver SIP
configuration parameters to the SIP handset whenever a SIP handset
is powered-up. The location of the SIP TFTP server is separately
specified in SIP handset administration parameters (See Chapter 2
SpectraLink 8020/8030 Wireless Telephone Configuration, section The
Admin Menu.) Normally, the SIP TFTP server is the same as the
network TFTP server, see above.
NTP (Network Time Protocol) Server
If WPA Enterprise security is used, the handset will confirm the PEAP
certificate has a valid date and time with the NTP Server on the
network, if one is available. If an NTP Server is not available, the
certificate will be assumed valid and operate accordingly.
Authentication Server (if using WPA2 Enterprise)
A RADIUS authentication server must be used to provide
username/password-based authentication using RSA certificates for
PEAPv0/MSCHAPv2 or PAC files for EAP-FAST.
