Re: wireless phone problem

Which IP phone? If the problem is when they are on the same AP only and using autonomous AP, then ensure that PSPF is not enabled. RTP will stay on the AP and will see packets to/from the distribution system. Of course will need something to respond to the ARP before RTP is estabilished.

So would want to ensure that proxy ARP is enabled on the AP as well.

Re: wireless phone problem

If using 4.0, would ensure you are using 4.0.217.0 or later. Some fixes in regards to packet aging and CCKM in that release.

Also can refer to 7921 deployment guide @ where the most data would apply to 7920 as well.
