"Leaving Service Area!" on Cisco 7925 Wireless Phone

Unanswered Question
Sep 10th, 2009

Having issues with a Cisco 7925 Wireless Phone on Call Manager 4.2(3)

This is the first one we have set up.

Even when we are sitting still, right next to the AP, it still periodically says "Leaving Service Area!" on the phone.

We were thinking it might have something to do with the beacon.

Any ideas?

I have this problem too.

Hi David

we have exactly the same problem. Did you find any solution since then?

Hi Dominic,

My apologies for taking so long to respond.

Yes, we did find the solution to the problem. Hope this works for you also.

On the WCS (Wireless Control System), go to...





Within here, you should see "Noise/Interference/Rogue Monitoring Channels". It will probably be set to "All Channels".

Change this to "Country Channels", update/save the change.

Repeat this for all the controllers you have.

This worked successfully for us, eliminating the "Service Area" issue completely on our 7925's.

Good luck!

Hi David

thanks a lot for your answer. I think we also solved the problem by disabling the higher data rates in 802.11a (36, 48 and 54 Mbps). But if not, we will try your solution.
