When making an outside call, my DAHDi extensions all ID themselves with the correct number, but my single IP phone refuses to do so. It comes up as “Anonymous” <0000000000>.
There is one bizarre exception to this: when I call my voip provider’s 911 test number it IDs correctly. Every other cellphone and land-line it calls winds up showing anonymous or private.
Can anyone suggest what might be wrong?
