Planning
U-NII middle band (5.25-5.35)
U-NII upper band (5.725-5.825)
The United States also allows for transmissions in the ISM regulatory domain on channel 165,
whose center frequency is 5.825 GHz which is at the upper edge of the upper U-NII band. The
802.11a implementation on the wireless handsets is based on U-NII regulations and do not
communicate on channel 165. Therefore, it is important not to configure any WLAN Access
Points for operation on channel 165.

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, Avaya 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.
- Necessary traffic for instance DHCP must be allowed, while all other traffic is denied.

Sample Access Control List

The following is a sample ACL for a voice VLAN named VLAN120.
set security acl ip SpectraLink permit udp 0.0.0.0 255.255.255.255 eq
68 0.0.0.0 255.255.255.255 eq 67 set security acl ip SpectraLink
