I have been putting in new cisco air-lap1131 access points along side existing cisco air-1220 APs. The problem we are now facing is that the avaya wireless 3620s drop calls when switching from the old to new new APs as you move around the facility. The phone gets a avpp error. Has anyone had this issue? The network group says its a telecom issue and the telcom groups says it a network issue. living in the middle can be so much fun!!! Thanks
