Different ring for incoming, transfered, and internal calls


I have a client that is interested in their internal calls having a different ring from the default incoming call. Right now I have a ring group that rings everyone in a small office. So when someone calls they all ring. They want a different ring from internal extension to extension, and also a third ring for a transfered call. What is the easiest way to do this?


if you look there are many posts that address this theme, some very recent


A quick hint is to leave the incoming ring at default and change the others.


If the phones are the same, I think it is best to create a rule in the phones with a sound for the numbers of interns and others as they come from factory


thanks for the replies
