Greetings!
I have a retail store chain that I'm implementing VoIP, and everything is working well with my current implementation plans EXCEPT for what I guess could be considered a failover scenario, although it's more like a mobility scenario for my use. Here's the scoop...
At the home office, I have a 2921 ISR setup with EIGRP and DMVPN, and inside my network is a UCM 7.1.5 server. At each of my stores is an 881W ISR with EIGRP and DMVPN reaching back home. At each site, I use 7925G wireless phones. I've done all my homework along the way and am getting GREAT performance and stability on this.
The issue comes into play with my mall kiosk stores (versus a traditional in-line store), in which their kiosk and my back room office/storage are close enough proximity to each other that my store employees would like to to just walk from one to the other. All of the wireless settings on the 881W's are setup the same, so that piece of the transition can happen, BUT when the phone transitions from one ISR AP to the other, the call of course drops or hangs. Each 881W is on a separate IP subnet, and so I'm guessing that the timing for an AP transition and UCM registration are taking too long.
So this is why I'm reaching out here... is there any way to optimize this to make it transition better?
