We have a client who is still paying for an ISDN BRI on their AT&T bill. Of course its in a conference room and it has not been used in over 2 plus years. I want to see if I can buy test equipment to see if it still works so looking for test gear recommendations.
I am also concerned that AT&T can no longer actually produce this technology from this particular CO. The tariff ended in 2006 and it listed as obsolete in 2013 by AT&T. Its in the state of Kentucky so if I could get any help here it would be appreciated. Any suggestions on how to go about confirming whether or not AT&T can still actually produce this.
Thanks, Bruce Brooks
