I worked with him also. He found the SBC was using a Nortel DSM100 switch not a 5ESS. He had SBC rebuild the curcuit to DMS100 Custom and its up and running. Your PRI was up before the porting of your lines and a program change. And it was set for 5ESS before the change and was tested and working. Right? You had made calls in and out on the channels that were up before the porting.
