I have Cisco CallManager 4.1(3) and Cisco 2811 router as a gateway between VoIP and PSTN. Cisco 2811 fowards all calls that begins with "9" to PBX. It's simple and traditional design, isn't it? Here is the dial-peer:
dial-peer voice 9 pots
translate-outgoing calling 34000
The problem: users don't hear busy tone when a PSTN number is busy. Telco sends DISCONNECT message through ISDN (with cause i = 0x8091 - User busy) and CCM just drops the call :(
How do I make CCM (or gateway?) to generate busy tone to Cisco IP phone users?
P.S. I've employed "voice call convert-discpi-to-prog always" command - no effect. I've also turned on "Retain Media on Disconnect with PI for Active Call" option in CCM. Nothing changed.

the softkeys. You enable or disable them via TCL. Here is the long
