Codecs
The WLAN Handsets 2210/2211 are compatible with the G.711 and G.729a/ab codecs. No configuration is required on the wireless handsets.
If the WLAN Handsets 2210/2211 are registered to the same BCM as IP Phone 200x sets, then the system administrator must configure only the subset of codecs that is supported by both the WLAN Handsets 2210/2211 and the IP Phone 200x sets.
If it is necessary for the IP Phone 200x to use a codec that is not supported on the WLAN Handsets 2210/2211 (for example, G.723.1), the wireless handsets must be configured on their own separate node.
Jitter buffer
The WLAN Handsets 2210/2211 do not support a configurable jitter buffer. If they receive the Jitter Buffer Configuration UNIStim message, the command is ignored. Any adjustment to the jitter buffer setting has no effect on the handsets.
RTP and RTCP
The WLAN Handsets 2210/2211 do not support RTCP. If RTCP packets are sent to the phone (these are actually sent to the WLAN IP Telephony Manager 2245), they are discarded. When the handsets are queried for their RTCP statistics, the handsets respond with 0 for jitter, 0 for latency and 0 for packet loss.
IP Phone 2004 mapping
The WLAN Handsets 2210/2211 emulate the IP Phone 2004. All IP Phone 2004 functions and messaging features are supported, where possible. The speakerphone function and functions that require use of the volume keys are not supported. See Feature limitations on page 75 for more information on the limitations of the WLAN Handsets 2210/2211.
The large screen area of the IP Phone 2004 and its numerous keys are mapped onto the smaller screen and fewer buttons of the wireless handsets. The button mapping from the IP Phone 2004 to the WLAN Handsets 2210/2211 is designed to preserve nearly all of the functionality of the IP Phone 2004 within a small, mobile device.
Feature and key assignment
The line keys of the IP Phone 2004 are numbered 1, 2, 3, 4, 5, and 6, and are situated to the left and right of the display screen (see Figure 9 on page 58). These IP Phone 2004 line keys are mapped to the LINE button on the WLAN Handsets 2210/2211 (see Figure 10 on page 59).
