Audio problems on conference calls on MSI/x-GBL boards
Some sites may experience a problem with noise generated as a conference call progresses.
Alternate firmware is available that fixes this problem.
Note: Instead of noise, other sites may notice an echo that worsens during the conference call.
For those sites the normal firmware installed with the Intel Dialogic drivers is recommended.
To install the alternate MSI firmware
1. Stop the TeleVantage Server, if it is running.
2. Back up the existing MSI firmware file so that you can revert to it if necessary. The
default location is
C:\Program Files\Dialogic\Data\msi240.fwl .
3. Copy the new MSI firmware file from the Intel Dialogic CD:
Drivers\Support\MSIFirmware_FR32\msi240.fwl
4. Restart the TeleVantage Server.
