Sorry I didn't explain my problem to well. We use 9150s and RLCs to connect to our Option 11c PBX. The problem is that the 9150s immediately bypass our PBX and dial out the backup PSTN line for that box when 911 is dialed and there is no way to turn off the feature as far as I have been able to find.
That is why we needed to change to the 8 instead of 9. I have implemented Gene's instructions for SPN 11 AND SPN 811 which should help alleviate some of the problem, but I need 911 back.
thanks,
JL
