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.
