the devices we use, that register to FreePBX, are some Grandstream ones.
I have googled and searched all the forums but I couldn’t find any solution to a demand I had from the users:
When someone calls them and the phone rings, they want to check who is the caller (name, phone etc) and they want to silent the call ringing but without pressing the “volume down” button multiple times while it still rings.
That way, the caller will stay on his speaker waiting for the phone to be picked up, but the callee will be ignoring him without the caller knowing.
The DND button won’t do, once it doesn’t do anything while the phone rings. In general, it notifies ALL callers as line busy, while we want the choice to be done individually per call by the user.
I’ve thought that I could forward the call to a virtual extension, so it will ring forever in that extension… But I can’t find any way to transfer the call while it rings on my extension.
