I’d like to add a button on sangoma phone that play an announcement.
You press the button play the announcement.
the idea is the receiver is busy doesn’t want to answer the phone, he press the button the annoucement say to the caller “hey leave me alone call me later” and hangup. And your back for receiving new call
Annoucement do that but how to triger it from a button on the phone.
I coud use Do not Disturb but it"s a toggle button you have to do it again to receive phone call
Where should I look for?
Thanks for your help.
