Essential Installation Pointers
You must update the software with the most recent code.
• Visit http://www.polycom.com/usa.en/support/voice/wi-fi/spectralink_8002_wireless.html.
Additional information about updating handset code is in Chapter 3 Software License and
Protocol Management.
WMM QoS must be supported and enabled on the Wi-Fi access point(s).
• When using the SpectraLink 8002 Wireless Telephones, WMM QoS is mandatory to ensure
voice packets are delivered in a timely fashion. The AP must have WMM enabled. If WMM is
not enabled or if the AP does not support it, the handset will stop and display an error (e.g.
No Net Found) after firmware update.
• Be aware that not all APs enable WMM by default. In fact, many APs require updated
firmware to support WMM. Follow the AP’s manufacturer instructions to ensure WMM is
supported and enabled.
Data APs may not support VoWiFi.
• The 8002 handset has been tested with many SMB access points. We have found that
VoWiFi performance varies between AP models and even firmware versions. An AP being
used for data does not guarantee satisfactory Voice over Wi-Fi performance.
• We recommend that you update to the latest AP firmware version if possible. If you
experience unexpected behaviors, try a different AP type.
A TFTP server must be on the local network with the SIP configuration files present.
• A TFTP server is a required component of the LAN. The SIP configuration files (and the
handset code) reside on the TFTP server and the handset retrieves the SIP files at every
power up. It is not recommended or supported to have the TFTP server or call-server across
a WAN.
• The handset must be configured to point to a TFTP server for the SIP configuration files.
This is accomplished by setting the handset for DHCP or by using static IP addressing. See
Chapter 2 SpectraLink 8002 Wireless Telephone Configuration, section Network Config.
• If the handset cannot find the files, it will stop and report an error.
