My Cisco 2851 IOS need support CME or not?

No need to configure CME. However, you may want SRST in CME mode, so yes.

Thks all for support,

I changed my gateway to H.323, and config:

!

application
  service aa flash:its-CISCO.2.0.1.0.tcl
  paramspace english index 0
  paramspace english language en
  param operator 6000
  paramspace english location flash:
  paramspace english prefix en
  param aa-pilot 6500

!

dial-peer voice 1 pots
description incoming_call_from_PSTN
service aa
incoming called-number 6500
direct-inward-dial

and

R1#show flash

System CompactFlash directory:
File  Length   Name/status
13   6627     its-CISCO.2.0.1.0.tcl 
14   457580   en_welcome.au

When I call from PSTN, i don't hear anything

Sep 17 12:32:28.887: ISDN Se3/0:15 Q931: TX -> CALL_PROC pd = 8  callref = 0x808A
        Channel ID i = 0xA98384
                Exclusive, Channel 4

*Sep 17 12:32:29.303: %IVR_MSB-3-NOPROMPT: Could not create IVR prompt
  flash:en_welcome.au
  errno=0=Can not recognize the file format

What 's file .au format? I did use Goldwave software to make audio .au file.

You are not using the correct audio file parameters. For easy recording from any phone, check my page at http://www.ciscoscripts.com

Thks P,

But after check audio format ok (no received message IVR Prompt) , next step, I still don't hear anything.

and here's event-log:

I check TCL Scripts file show:

_wecome.au, _en_dest.au

My IOS:

c3745adventerprisek9_ivs-mz.124-15.T1.bin support TCL Scripts?

Do you know, what Cisco IOS support TCL Script auto attendant?
