As usual, a substantial amount of my work time is being taken up with Asterisk programming and issues.  There was a T1 attached to one of the servers that had a channel a bit out of whack.  Any call coming into the 5th channel would ring in and “hang”.  From the calling side, it was dead silence.  From the servers point of view, a call came in without DNIS or CID.  It tried to play the “ss-noservice” message, but the audio would not be heard.  The carried claimed it was an “equipment issue” on our side (that restarts never solved), but after some testing (and a reset by Qwest), the problem suspiciously disappeared and has not returned.  Now, back to creating more custom IVR menus.
