My company has changed names recently. One of our offices says when we call them their phones show the old name. I have tested our lines through SBC and they all show the new name. We have 2 T1's for long distance through Sprint. Sprint says the problem is not with them. Is there somewhere on my switch that is sending the old name? I have it narrowed down to long distance calls, so it must be coming from calls made over the T1's.
