Appendix D – Setting up MultiVOIP as CallFinder-DID
MultiVOIP® Voice/Fax over IP Gateways 151
Configuring hardware for DID channels for MVP410 or MVP810
For each channel that is going to use the DID interface type, change the jumper on the MultiVOIP circuit card.
DID is not supported on the –SS or –FX models or MVP410 and MVP810 models older than revision C.
1. Disconnect power. Unplug the AC power cord from the wall outlet or from the receptacle on the MultiVOIP
unit.
2. Using a #1 Phillips driver, remove the three screws that attach the main circuit card to the chassis of the
MultiVOIP. You can locate these screws on the back of the unit.
3. Pull the main circuit card out about 5 inches. The power connection to the board prevents it from being
removed entirely from the chassis.
4. Identify the channels on which the DID interface is used.
5. Position the jumper for each DID channel so that it does not connect the two jumper posts. For DID
operation of a VOIP channel, the MultiVOIP works properly if you remove the jumper altogether. Doing so is
not advised because the jumper might be needed later if a different telephony interface is used for that
VOIP channel.
