Gain adjustment

The handsets ignore any UNIStim messages that adjust the loss plan of the wireless handset.

Programmable rings and tones

The wireless handsets support alerting cadences but only a single alerting frequency.

The wireless handsets have the same call progress tone capability as the existing IP Phones 2004.

In/Out of Service tones

When the handset completes registration with the Call Server, it plays the In Service tone. When the handset loses connection with the Call Server and resets, it plays the Out of Service tone.

Virtual Ofﬁce

The handsets support Virtual Ofﬁce. For more information, see Features and Services Fundamentals (NN43001-106)and IP Line Fundamentals (NN43001-500).

Branch Ofﬁce

The handsets are supported in a branch ofﬁce location using the Branch Ofﬁce feature. Branch Ofﬁce refers to the Media Gateway 1000B and the Survivable Remote Gateway (SRG). A WLAN IP Telephony Manager 2245 and supported APs must be installed at the branch ofﬁce location. Branch ofﬁce wireless handsets do not require wireless handset infrastructure in the main ofﬁce.

The wireless handsets in a branch ofﬁce conﬁguration behave like an IP Phone 2004 in the Branch Ofﬁce feature. The wireless handsets are administered in the same manner as the IP Phone 2004. The display on the wireless handsets is almost the same as the display on the IP Phone 2004, with one exception—the Local mode display.

Local mode display

The default state of the wireless handset is Standby. To determine whether the wireless handset is in Local mode, press the off-hook (Green) or the MENU keys on the WLAN Handset 2210/2211/2212 or the soft keys and the Nav keys on the WLAN Handset 6120/6140. Pressing these keys changes the state of the handset to Active Idle or Active Off-Hook, therefore putting the handset in communication with the primary Signaling Server.
