Analog line remains active even after call has ended

[Alex Tsonis]

Hello,

I have a scenario where an analog device (sccp controlled and connected to a cisco analog voice gateway) performs a call to an IP phone and when the IP phone terminates the call, the line remains active in the analog device.

Note that all calls are internal and do not go to PSTN.

I have tried to change the voice port timeouts, but with no luck.

Can someone help me? Alternatively, is there a possibilty to set a "timer" that will always drop the call after specific amount of time? E.g. 45 seconds?

Thank you

Operation center phones, is it a part of the same call manager ? 

Lift phones is it a analogue phone mounted to the lift or it’s an inbuilt device with the lift ?

The operation center phones are 7821/8851 IP Phones, registered in the same Call Manager.

The lift phones are phones mounted behind the button panel of the elevators
