SpectraLink 8002 Wireless Telephones Configuration and Administration (SIP)
Domain Name System (DNS), an
In DHCP mode, the SIP handset will use DNS to look up an address for the logical name “siptftp” to locate the SIP TFTP file server. If this logical name is undefined, then the address specified by option 66 is used for the SIP TFTP server.
ESSID
Select the option that will enable the handset to acquire APs with the correct ESSID (Extended Service Set ID, aka SSID) each time it is turned on.
Note about Automatic Learn options: Broadcast ESSID must be enabled in the APs for ESSID learning to function when multiple ESSIDs can be seen by the handset from one location. Overlapping wireless systems complicate the use of ESSID learning as the handset in an overlapping area could receive conflicting signals. If this is the situation at your site, use Static Entry or Learn Once in an area without overlapping ESSIDs.
*Learn Once Allows the handset to scan all ESSIDs for a DHCP server. Once either is found, the handset retains the ESSID from whichever AP it associates with at that point. When overlapping wireless systems exist, the Learn Once feature allows the handset to use only the ESSID established at first learn at all subsequent power ons. This ESSID is retained by the handset until the ESSID option is reselected in the Admin menu, thus erasing the stored ESSID.
Learn Always Allows the handset to automatically learn the ESSID at each power on or loss of contact with the wireless LAN (out of range). This may be useful if the handset will be used at more than one site.
Static Entry If the APs do not broadcast their ESSID, or if there are overlapping wireless systems in use at the site, enter the ESSID manually.
