One thing else about the EL... If you have this problem again, deleting the offending programming on the port and reprogramming doesn't always fix the problem. TS recommended to me that I renumber the extension having issues, move it to another port, reprogram the correct extension on the orginal port and then delete the bad one. There's something that sometimes stays married to the port that can cause problems even though you deleted the programming of the extension but if you move it to another port in programming the problem follows to the new port and leaves the original ready to go. :shrug:

Thanks, jonmyk. I do need this as a sub, so i may have to try that. I've confirmed a tech is to be onsite tomorrow to install a second 4150. I'll program it first to see if problem happens on a different digital port.

Issue resolved. It was COS. I went back and copied the original COS to COS 13, then added enhanced Sub to COS. Both 4150s work. One issue regarding functionality: Customer ordered these from us "blind" thinking they would also get wakeup call capability on the 4150s. Apparently LW17 can't get wakeup on sub-att sets. Thanks, everyone.
