I have customers that are all wireless, they don't have Ethernet wiring in the offices. Anybody putting out 10, 20, 100, etc... of these J179 with wifi on a system? I have tested a couple with zero issues, but have not been wanting to do an all wifi install. Does Avaya have any guidelines on the number of wifi J179's? Does it matter? Should it be avoided in high numbers? I can work around the number of devices connected per wifi AP, but was curious how performance (i.e. simultaneous paging through the phones) would work, any gotcha's, etc...
