B-ACD with Non CME 2900 series H232 Gateway

I got a request to block non-notice (calls with blank calling numbers) calls with voice prompt. The calls are comming Cisco 2921 price   from BRI configured in a 2921 H323 gateway.

For this I am thinking of putting BACD application with a welcome prompt for the caller and drop through after that to a random number to end the call. This is only the requirtement and not planing to use the ACD feature of the script.

Can I do this with a h232 gateway 2921 that is not CME (only CME-SRST)? is there any other better way to do this. In normal mode calls are going to CUCM 6.1 using voip dialpeers. Callmanager related configurations are not shown here.

Though you could do it with BACD & a drop through, I wouldn't do it like that.  A cleaner solution is to throw the call to your AA (Unity, CUE, IPCC).

Add other h323 peer stuff here....

What this does is match peer 1 inbound for any inbound POTS call that doesn't contain an ANI.  It then takes that call and translates the DNIS to a special pattern, and sends it to CUCM.  Then configure CUCM/Unity/whatever to router 8675309 to an AA that say 'Hey your call is being blocked because you aren't presenting CLID  Cisco 2951 price   ' and hang up.
