Almost all of the KTAS telephones was made with a jumper, or strap to split the ringer-circuit from the speach circuit. The line terminals will often be named La or 1 and Lb or 2. the ringer circuit is connected with a strap between K and EK or La.
In seres with the wire you connect to K you should put in a resistor of 3-4 kiloohms.

Then blue with white to Lb, orange w white to K and wite w blue to La

colors are based on this: http://www.wppltd.demon.co.uk/WPP/Wi...telephone.html

If you show some pictures of the telephone it may help.
