Polycom SoundStation 2W - Analog Port Disconnect Issues

[maxse]

After completing a call the system does not disconnect and plays a tone/hum. I have adjusted the settings in Manager 9.1 (upped the disconnect to 255) with no success.

You have to manually clear down the call, it's an analogue device, so works by manually closing it's own switch hook, the system can't do that for it.
You could try and make it an IVR port to see if Polycom designed it to detect the break in loop current or not, if they didn't it's not Avaya's fault

That tone after an analogue disconnects but does not hang up is called howler tone.
It's annoying because it is supposed to be.
It is possible to crash a system, not just IP Office, by leaving analogues off hook.
Many system features are processed when the phone system is idle.
NECs used to have a system refresh where it checked the status of MW lamps etc. It cannot do this if an extension has been left off hook.
Hence manufacturer puts in howler tone to force you to either act, or learn to live with a non threatening stimulus.
