[asterisk-users] Wifi - Managed access points...

[Wai Wu]

Thanks. It make perfect sense. I was just curious why the manager app is needed. Since the phone can see 4 AP at the same time, when it wants a call to be handed over to a different AP, couldn't it just send a re-invite to Asterisk and call it a day?
