might indicate that a phone is off hook (FXS) or that an incoming ring is present (FXO). The IFM receives operating instructions from the voip’s main processor. For example, the IFM might be instructed to ring the phone (FXS) or seize the line (FXO). The IFM contains a codec (coder/decoder) to convert the incoming audio to a PCM stream (pulse code modulation) which it sends to the DSP (digital signal processor). The IFM’s codec also converts outgoing PCM to audio.
The firmware of the IFMs will change from time to time and you may need to upgrade the firmware on your MultiVOIP unit. To do so, follow these instructions.
1.In the System Information screen of the MultiVOIP Configuration software, check the version number of the IFM firmware already installed on the MultiVOIP unit. Write down the version number.
2.Exit the Configuration software program. The MultiVoip Configuration program must be off when invoking the Download IFM Firmware command. If it is on, the command will not work.
3.To invoke the Download IFM Firmware command, go to Start Programs MVP____ x.xx Download IFM Firmware.
4.A warning window will appear: “Downloading IFM Firmware will reboot the MultiVOIP. Do you want to continue?” Click OK.
4.The “Boot” LED on the front panel of the MultiVOIP will come on.
5.The software will search for an IFM firmware file to use to upgrade the system. If the file found represents firmware newer than that already installed on the MultiVOIP (or if you want to overwrite the same version of firmware) click Open.
