Good afternoon.
I have a GDS3712 installed at a customer’s house
My client doesn’t like the “bell” sound when you press the gate button.
Can I change this sound? What options do I have?


What firmware version loaded with your GDS3712?

Please upgrade it to the latest version from the official website:

After that, just follow the User Manual and import your own ringtone based on the requirement:

Hope this helps. Thank you for using Grandstream Access Control Products.
