Network planning
You must ensure that all connections and interfaces for the IP Telephony
network are configured as full-duplex. Duplex mismatches anywhere on the
WLAN can cause the wireless IP Telephony system not to function normally.
Network recommendation
To maximize security and to minimize accessibility for unnecessary traffic
to reach the WLAN Handsets, Nortel recommends that you adopt the
following measures:
• Create a separate VLAN for voice traffic and map the handsets to this
VLAN to mask the handsets from other devices on the network.
• Implement Access Control Lists (ACLs) on the WLAN infrastructure to
contain the handsets but deny other traffic.
— The WLAN IP Telephony 2245 uses IP protocol 119 and
encapsulates both signalling and media (RTP) into a common packet
format allowing the access points to prioritize legitimate handset
traffic.
