We have two remote locations to our hospital, one with a S100 on S100-30.14.0.97 that the trunk still works just fine. The S50 that we just upgraded to S50-30.14.0.127 the trunks will not work. We have tried removing them and recreating. We also notice that the S50 has this message reporting on the AVAYA that was never there and does not happen with the S100

How can we revert to 30.13.0.15 which was the last working firmware on the S50 or possibly 30.14.0.97 that is still working OK on the S100?
