Introduction
The WLAN IP Telephony Manager 2245 acts as a proxy for the wireless
handsets and provides several services for them. It is connected to the
same subnet as the wireless handsets. The wireless handsets always
communicate voice and signaling directly with the WLAN IP Telephony
Manager 2245, using the proprietary SpectraLink Voice Protocol (SVP).
SVP is required for quality of service (QoS) because the current
IEEE 802.11a/b/g wireless LAN standard provides no mechanism for
differentiating audio packets from data packets. This standard is undergoing
revision to version 802.11e to provide functionality in an industry standard
similar to SVP, therefore ensuring high-quality voice in a mixed-client
environment.
Functional description
The WLAN IP Telephony Manager 2245 provides the following services
to the handsets:
• It acts as a proxy for every wireless handset; that is, all UNIStim
signaling and RTP media to and from the wireless handset pass through
the WLAN IP Telephony Manager 2245. Except for the initial DHCP
and TFTP sessions, the wireless handsets only communicate with the
WLAN IP Telephony Manager 2245.
