Ruggedised Phone won't hang up!?

[Stroller10]

Hi Guys,

MDSH> ts_about
====== MX-ONE Telephony System ======
Version: 3.2 SP6 build7

I have a steel type ruggedised analog phone. Once plugged in (even when hook is on) the line opens and stays open until line lock, unplug the line and repeats the same action.

When I plug a standard analog phone in it works perfect.

Any help??
