553-3001-304 Standard 3.00 September 2004
The longer than normal jitter buffer setting is reasonable since extra jitter is
introduced by the RF portion of the link.
RLR and SLR
The Wireless Handsets 2210/11 do not support UNIStim messages used to
adjust the Receive Loudness Rating (RLR) and Send Loudness Rating (SLR)
of the wireless handset.
RTCP
WLAN Handsets 2210/2211 do not support Real-time Transport Control
Protocol (RTCP). Incoming RTCP packets sent to the wireless handsets are
actually sent to the WLAN IP Telephony Manager 2245 and are discarded. If
the wireless handset is queried for RTCP parameters, the wireless handset
returns dummy values of 0 jitter, 0 latency, and 0 packet loss.
Gain adjustment
The WLAN Handsets 2210/11 ignore any UNIStim messages which 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.
Virtual Office
If a wireless handset is forced off a VTN due to a Virtual Office (VO) login
of another IP Phone, there is no way for the wireless handset to reconnect to
the Virtual TN (VTN). This can be avoided by using the Virtual Office Login
Denied (VOLD) and Virtual Office User Denied (VOUD) Class of Service on
the VTNs used by the wireless handsets.
