thanks for the replys.

Yes it it a MLS 12D telephone.
and yes the trouble follows even with a different known-good telephone - also MLS 12 btn.

Have already changed ports back at the KSU, ( swapped 10 & 13) cant do alot of port swapping due to office activity.

To be honest, Im just hoping this customer replaces this system
