Call waiting and voicemail problem


I recently setup pbxinaflash. For the most part things are working as advertised. I am having a couple of problems that I cannot find solutions to.

The first problem is that when there is a voicemail message, I do not get a stutter dialtone on my extension. Can someone direct me how to troubleshoot and repair this problem?

The 2nd problem is that when I am on a call and a 2nd call comes in, I hear the call waiting tone but the party I am talking to can no longer hear me. I have to hang up and place the call again.

Does anyone have any ideas how to troubleshoot and repair these problems?

The system is running:

  • PBX in a Flash Version :
  • FreePBX Version :
  • Running Asterisk Version : Asterisk
  • Asterisk Source Version :
  • Dahdi Source Version :
  • Libpri Source Version :
  • Addons Source Version :

The calls are coming in or going out on several different sip trunks provided by several different providers.

The extension I am talking on, is connected to the system via a Digium TDM400 FXS port and Dahdi.

So far my extension is the only one on the system. This is a new system that I would like to add more extensions to but I have to resolve these problems before I can move on.
