4-6 Mobile Handset Configuration
MH110/MH120 IP Wireless Telephone Setup and Administration Guide - Revision 1
ESSID
Select the option that will enable the Mobile 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 access points for ESSID
learning to function.
Overlapping wireless systems complicate the use of ESSID learning as
the Mobile 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 Mobile Handset to scan all ESSIDs for a DHCP
server and/or TFTP server. Once either is found, the Mobile Handset
retains the ESSID from whichever access point it associates with at
that point. When overlapping wireless systems exist, the Learn Once
feature allows the Mobile Handset to use only the ESSID established
at first learn at all subsequent power ons. This ESSID is retained by
the Mobile Handset until the ESSID option is reselected.
• Learn Always: allows the Mobile 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 Mobile Handset will be used at
more than one site.
• Static Entry: If your access points do not accept broadcast ESSID or
if there are overlapping wireless systems in use at the site, enter the
correct ESSID manually.
License Management
License Management lets you select the VoIP protocol that your site is
licensed to download and run. The Protims protocol to use for the
MH110/MH120 UNIVERGE WL Mobile Handsets is 013. Any other
protocol will cause the Mobile Handset to malfunction. After selecting
the correct protocol for your site, you should upgrade the software for
the Mobile Handsets.
REFERENCE
Refer to the “Configuration Note” for your access point or call your access point
vendor for specifics.
