Product specifications

STEP 7. After all the connectivity is verified you should be able to demonstrate the functionality of the 7921 by making calls to a
Desktop 7960 phone and other phones if available. Phones extensions examples are shown in the figure above.
Note 7921 clients should be freely moving (roaming) around the demonstration room and observe no latency in the
communications since Fast Secure Roaming (CCKM) was configured on the 7921. The 7921 phone will be auto configured in
the Voice system. You may want to add names to extensions as you wish.
Client Failover
STEP 1. Place a call from the 7920 Wireless IP Phone to the 7960.
STEP 2. Answer the call on the 7960 and put the call on mute.
STEP 3. Note which AP the 7920 is associated by looking for a fast blinking Ethernet activity light on the AP. Or you can look in
the WLAN Controller or CCA
STEP 4. Disconnect the Ethernet cable from this AP. Talk into the 7920 while doing the demo.
STEP 5. Notice that the phone call will stay active and only takes a second to failover to another AP. The voice interruption should
be very minimal.
STEP 6. Verify 7921 phone connection in the Topology View.
