Ok, I removed key 2 & 3 from the five phones and then added key 2 & 3 with lhk 4 on tn 65 5 and then tested, it worked fine, and the I I did the same for the rest of the phones and tested and is now working fine. Question I have now is when adding the keys I started in the middle of the tn range and it did not work, wiped the keys and program from starting tn and work up and it works fine, is that what tnphoneman ment by sequential?
