I measure 6.8V on dial-tone, dropping to 5.81 when dial-tone is replaced by N/U tone. This is on my Ericsson N1071 which has the same gizzards as a 332, but has a handset type 164 (3-terminal) not the 184 like yours. Not that the handset type should make a difference, of course.

So when you blow into yours on receipt of dial tone, and with 6V across it, can you hear your blowing in the receiver?
