handsets. It provides a number of services including a QoS mechanism, AP bandwidth
management, and efficient RF link utilization.
The WLAN IP Telephony Manager 2245 works with the APs to provide Quality of Service (QoS)
on the WLAN. All voice packets are encapsulated by the wireless handsets. The encapsulated
voice packets to and from the wireless handsets are handled by the WLAN IP Telephony
Manager 2245 and routed to and from a Call Server.
SpectraLink Voice Priority (SVP) is the QoS mechanism implemented on the wireless handsets
and APs to enhance voice quality over the wireless network. SVP gives preference to voice
packets over data packets on the wireless medium, increasing the probability that all voice
packets are transmitted and with minimum delay. SVP is fully compliant with the IEEE 802.11
and 802.11a, b, and g standards.
Avaya does not support use of ICMP Network Redirection with VoWLAN applications due to
degraded routing and network performance. The 2245 WLAN Handset, upon receiving an
ICMP redirect, will update its routing table and attempt to send packets through the new route,
however this is not instantaneous. As per the RFC, the route is not permanent and will
eventually revert to using the default gateway.
Each subnet, where the wireless handsets operate, requires at least one WLAN IP Telephony
Manager 2245. One standalone unit can process up to 80 simultaneous calls depending on
the model, as listed in
