[cisco-nas] modem not negotiating when receive ANI on ISDN/PRI

That's very odd.  The router shouldn't care what the
ANI is.

I'd get:

debug isdn q931
debug csm modem
debug modem

conf term
  service timestamp debug date msec
  modem call-record terse

Let's see what a good and a bad call look like.  Also
check "show run", "show ver", "show modem ver".
