We have various medium size deployments of Spectralink 8440 and most sites are experiencing the same thing - call drops during mid conversations.

We deployed the Wifi with the VIEW Certified Juniper parameters for 8440 and VIEW Certified software level for the Juniper WLC controller.

I have done some Wireshark captures on the wired network side in front of our VOIP server and I can see/hear that the voice just suddenly drops.

Has anyone else experienced this issue? It doesn't seem to matter if the handsets have full signal or 1 or 2 bars of signal, the result seems to be the same. We are running the latest firmware on the handsets. This almost seems to be a roaming issue on the handsets or on the APs - I'm unsure.


Anyone else experience this?
