I have a VIP 4286 on a Vista 10 board. Everything works on the on premiss phone but when I call from an off premiss phone the phone disconnects after hitting 9#. The on premiss phone is still connected and controlling system but it should be reversed. Disconnect on premiss and seize line for the off premiss. I know I went through this when I set up my Vista20 but forgot what I did to correct it. I tried different variations of wiring the RJ31X and also bypassing it and reversing 3 and 4 but still the same. Any suggestions? Thanks Jerry
