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

[Rodney Kreisler]

Cisco 5300

2 ISDN/PRI with ANI.  When a call comes in with ANI blocked then 
connection establishes without problem.  If ANI is NOT blocked, the 
modem will not initiate negotiation.  Sometimes the modem will 
immediately return to onhook state.  Other times the modem will stay in 
call setup for an indefinite period.

My thought is that this is related to modemcap but could find no 
supporting documentation.  Does anyone have a suggestion?

TIA
