CTX-100 w/RCOU/RCOS line cards and (3) BWDKU station cards.
One Ext.(#238) randomly calls the receptionist or operator (#200) on the intercom. This occurs about once a day or less. I have tried deleting the ext. and rebuilding it also moving to a different ext. (#248), the problem followed the change. Will a intermittent short in the ext pair cause this? I could meger this pair of wires or change to a different pair. I have looked for a short in punch down blocks and phone jack. Extension (#200) is a DK3020SD w/ (2) DADM3220's. The VM is a IES32 w/ 250 center port and 251 and 252 as VM ports. Thanks for any input, Lyle Roy
