Duplex mismatch

A duplex mismatch anywhere on the WLAN can cause the WLAN IP Telephony Manager 2245 to operate improperly. Double-check WLAN connections and interfaces to ensure that they are all configured as full-duplex.

Feature limitations

The following limitations exist for the WLAN Handsets 2210/2211:

The WLAN Handsets 2210/2211 do not have handsfree capability. Therefore, any feature which requires handsfree is not supported or only partially supported. For example, when there is an incoming call to an IP Phone 2004 set that is idle, but offhook, the set buzzes the handsfree speaker. This feature is not supported on WLAN Handsets 2210/2211.

The WLAN Handsets 2210/2211 do not support all of the buttons present on an IP Phone

2004. The following keys are not available:

Expand to PC key

Navigation (Left, Right, Up, Down) Keys

Headset Key

Handsfree Key

Services

Any operation that requires those keys is not supported.

Any feature that requires scroll buttons is not supported. For example, Feature * 900 is not supported on the WLAN Handsets 2210/2211. The use of Call Logs and set-based administration is also limited due to the lack of up and down scroll buttons (for example, you cannot erase old logs from the Call Log).

The WLAN handsets do not have a signal strength indicator.

The WLAN handsets do not support the Net6 feature.

Feature F*6 affects the display, but does not change the ring tone.

Feature F*7 does not affect the LCD display.

The WLAN handsets can access SBA, but they cannot navigate the menus.

The set display is 4 lines by 19 characters. Therefore, some lines may be truncated or compressed by a special compression mechanism. Also, the softkey labels are four characters wide instead of seven characters as on an IP Phone 2004.

The WLAN IP Telephony Manager 2245 can block calls due to bandwidth constraints on an AP without notifying the BCM. The caller hears ringback, and the call-forward-no answer treatment will be applied (for example, go to voicemail).

If the call originates from a wireless handset that is on a bandwidth-restricted AP, the caller hears a warning tone (three “chirps”) and the call is disconnected.
