i wants to make some changes in asterisk voice mail system, so i modified the source code in app\_voicemail.c, now i need to create a special DTMF input to browse the old messages folder, i found the follwoing function that used for changing folder:

[code]case ‘2’: /\* Change folders \*/  
if (useadsi)  
adsi\_folders(chan, 0, “Change to folder…”);  
cmd = get\_folder2(chan, “vm-changeto”, 0);  
if (cmd == ‘#’) {  
cmd = 0;  
} else if (cmd \> 0) {  
cmd = cmd - ‘0’;  
res = close\_mailbox(&vms, vmu);  
if (res == ERROR\_LOCK\_PATH)  
goto out;  
res = open\_mailbox(&vms, vmu, cmd);  
if (res == ERROR\_LOCK\_PATH)  
goto out;  
play\_folder = cmd;  
cmd = 0;  
}  
if (useadsi)  
adsi\_status2(chan, &vms);

```
		if (!cmd)
cmd = vm_play_folder_name(chan, vms.vmbox);

```

vms.starting = 1;[/code]

how can i modify it to press 2 for old message directly

I think you need to use the developer mailing list or IRC channel.
