Configure Modemulator Dialing Directory
The Modemulator makes a peer-to-peer connection to another Modemulator, which emulates a
dial-up modem connecting to another dial-up modem. In both cases, the calling device has to
know the "number" of the answering device.
For an M2M system based on dial-up modems and PSTN networks, the telephone service provider
assigns a phone number to the destination, and the User (or software application) commands the
calling modem to dial the phone number of the destination modem.
For an M2M system based on Modemulators and cellular networks, the MVNO that provides the
cellular data service will assign a static IP address to each device (CDMA) or SIM (GSM) on the
account. That IP address is the "number" that the calling device must know.
In order for the Modemulator to be a drop-in replacement for dial-up modems, it has to accept a
command to dial a PSTN phone number, but translate that number into the IP address of the
destination Modemulator. That translation is done by the Modemulator dialing directory.
