hbiss is correct in his posting about digital buttsets . One is not made for the following reason . Just within the family of mitel digital sets a ss4dn will not work on a port porgrammed as a ss4 . A ss420 will not work on a port programmed as ss4dn . A ss4025 will not work on a port programmed a ss420 . A ss4150 will not work on a port programmed as a ss4025 . I can see in the future an IP buttset once every IP set is using the same PROTOCOL .
