We plan on having three AP's for our desired coverage area with no WLC. Building A has inside AP, then outside has an AP for coverage between Building A and B, then Building B also has an inside AP).
If we set these up via Extended Service Set (i.e. all three AP's sharing the same SSID) will wireless VOIP calls drop when person using 7921 voip phone moves between buildings? Can you roam in this scenario without dropping a call? If you cannot roam, is their a "work around" we can use that will not required a WLC in the picture?
thanks in advance,
