CP-7920 - 2 Wireless VOIP drops when calling each other

Unanswered Question
Dec 10th, 2007

I can call from a hardline to a wireless voip phone, but the moment I bring out my wireless phone and call theirs, the phone rings but no voice is heard. I tried on different AP and same AP with same results.

Let me rephrase this. The call doesn't drop anymore the call seems to ring and is established, but I dont hear anything. I tested if the phones can call seperate hardlines and the call is established and both phones work. They just have trouble calling each other.

I have this problem too.

So the issue is calling 2 7920s on the same AP? Ensure that peer to peer blocking (aka PSPF) is not enabled.

Also that proxy arp is enabled.

For WLAN controller, do "show network" and ensure that arpunicast mode is disabled.

For autonomous, configure "dot11 arp-cache optional".
