C optiPoint WL2 Configuration
This appendix describes the recommended configuration for the optiPoint WL2
wireless telephone with the HiPath Wireless LAN Solution. In addition,
corresponding configurations should be made on the PBX, if applicable.
Note: Update your optiPoint WL2 wireless telephone software to the latest
available firmware. The following information in this appendix refers to an
optiPoint WL2 telephone running firmware version 50.002.43.00079.
C.1 optiPoint WL2 wireless telephone configuration
To configure audio settings:
1. Launch your Web browser, and in the browser address bar type the optiPoint
WL2’s IP address. The optiPoint WL2 professional Handset page is
displayed.
2. In the optiPoint WL2 professional menu, click Admin. The Network: Profile
Selection page is displayed.
3. In the left pane, click Audio Settings. The Audio Settings page is displayed.
4. Configure the following audio settings:
• In the Codec drop-down list, click G.711 preferred (normal quality).
The alternative G729 codec would only provide a small increase in
capacity at the expense of a significant increase in sensitivity to lost
packets and degradation of quality.
• In the RTP Packet Size drop-down list, click 20ms.
The 10ms setting would not improve voice quality, but it would
significantly decrease the per-AP voice capacity. The 30ms setting would
worsen the impact of lost packets while roaming.
• Clear the Silence Suppression checkbox. The Silence Suppression
option should be disabled.
