Old analog emergency phones 2

[pated66]

Is anyone using Ramtel phones with IP Office v500?
I'm at a university, so we have several dozen emergency phones around campus.
These were all connected to our old Ericsson system & had no issues.

Now, when you call out on the emergency phone, it does not disconnect on it's own. Only physically removing the plug will disconnect the call. Also, to program the phones, you call the extension, it picks up, gives a tone, then you enter 000 and the login security code.
The phones no longer respond with the tone when you call to the extension.

I've worked with Ramtel & they sent me a test unit of their newest model, which is a lower power unit than the old ones on campus. I had a call with them and my Avaya vendor and the voltage was one of the stand out items.

The new model phone, after programming it on one of my copper lines works fine.

Thoughts?

Set the analog station port type to IVR so that IPO sends disconnect supervision.

Modern systems run much lower voltages than legacy stuff, it cant be changed either

An analog phone signals an offhook by opening the circuit and a disconnect by closing the circuit. Saying that you can only disconnect by unplugging the phone (I.e. opening the circuit) does not make sense.
