FEATURE REQUEST: Auto-Hang-Up after opening door



Could you try to check the “Enable On Hook After Remote Door Opened” (by default disabled) in the “Basic Settings” page of “Door System Settings” to see whether it helps?

Thanks for using GDS products.


Hi GS_Guy,
this is enabled.
This should be work after remote open the door.
After calling we take a look to the preview and
we open by hand,
and how should the GDS know,
that the door was opend?
Many thanks Michael


@MichaelS: Unless the strike can provide signal to GDS (some stiker has status register to send out those information but the cost is super expensive), GDS can NOT know whether the door is really opened or not. All the GDS did (when this feature is turn on) is playing beep and strike operation noise will be transmitted back to the phone. Therefore I usually not use auto hand up (to see in the phone’s MJPEG or H.264 video, depending on phone used) to make sure the door opened and the guy already in, before manually hand up the phone (it is not so inconvenient once used to it).

Hope this helps. Thank you for using Grandstream products.


Hi GS_Guy,
sorry for further requesting from me.
I need an input from door contact
to stop the call from GDS to UCM ringgroup.
Door closed = contact closed.
Many thanks Michael


Since today the bell rings further
after open the doorhandle manually.
That´s annoying.
Please stop the call in my ringgroup
GDS to UCM and phones.
Thanks Michael


Actually IN2 with a door sensor (magnet) could be easily used for this purpose. All it needs (in a future firmware!) is an extra setting in the GDS config like “Hang up call when door = IN2 has changed to open”. Until then you can accept the call and hang it up without opening the door, then walk to the door and open it manually (this assume you are near the inside phone, which you might actually not be).

BTW: There is a spelling error in the web UI help pop-up that reads “hand up” instead of “hang up”


it´s not in


@MichaelS: Have you checked the “Basic Settings”: Enable On Hook After Remote Door Opened

This will allow phone to hand up after remote PIN opened the door.

But if someone ring the bell and call is established but not answered, then someone opened the door, then the door bell will keep on ring until time out (30 seconds). Because there is no signal feedback from strike to the GDS (unless the strike can do this), the GDS will keep on ringing until time out, this is unfortunately.

Or, you can enable “Enable Doorbell Button to Hang Up Call” , then the door bell is like a ON/OFF switch, press 1st time make SIP call open door, press 2nd time cancel the previous call. But then still falling to the previous case, if the strike NOT sending door opened electronic control signal back to GDS, GDS has no way to know the door is opened. This is still no solution.

Thank you for using GDS3170.


Thank you GS_Guy. Could you consider to add this reed/magnet feedback feature (see above)?

“Hang up call when door (IN2) has changed to open”

Likewise I have also suggested to implement a log entry/ notification/ warning when the door is left open for too long.
