Cisco Wireless VoIP Phones Integration

The current Cisco offerings for VoIP Wireless phones are the 7921 and 7925. The current security authentication they support and encryption:

• Authentication:
• Cisco Wireless Security Suite IEEE 802.1X
• Lightweight Extensible Authentication Protocol (LEAP) Authentication
• Protected Extensible Authentication Protocol (PEAP) MS-CHAP v2
• Extensible Authentication Protocol-Flexible Authentication via Secure Tunneling (EAP-FAST)
• Extensible Authentication Protocol-Transport Layer Security (EAP-TLS)
• Wi-Fi Protected Access (WPA) Versions 1 and 2; Personal and Enterprise
• Cisco Centralized Key Management (CCKM)

• Encryption:
• 40- and 128-bit static Wired Equivalent Privacy (WEP)
• Temporal Key Integrity Protocol (TKIP) and Message Integrity Check (MIC)
• Advanced Encryption Standard (AES)

So you have options under then 802.1X frame work to work with and you can still keep your higher level of encryption.

WORD TO THE WISE: If you do use 802.1X with AES on a VoIP phone you need to test this on your wireless network at length. Poor wireless network designs MAY cause longer delays while roaming and jitter or dead air can be expected during a roaming event. A protocol analyzer is very helpful determining this and troubleshooting if there is issues.

A recent troubleshooting event at a customer site i found that their network was causing a 1 - 2 second 802.1X auth. Something that should have been 20-100 mS. They had a tremendous amount of co- and adjacent channel interference.

I worked recently with a customer and we were able to get PEAP working on a number of BBs with server side certs. So you should be fine there, just google it lots of info can be found on that topic.

If you have a choice, i would check out the Ascom VoIP handsets. They are much better. Just my .02

not sure what you mean by separate channel. you should only use 1 6 11. 3-4 phones shouldnt be an issue.
