Western Electric 102 - Subset 634-A problem

[GTElover]

Hi Everyone,

Have a small problem, I have a Western Electric 102 (B1) stamped on the back.  I have managed to attach the subset to the phone (634-A), got it to produce a dialling tone, dial out and even got it to ring.  The problem is that when I dial out I get bell tinkle, is there a way to stop this?

Many thanks in advance
Matt
