MMGEOIP module

This module is a lightweight wrapper for the MaxMind GeoIP API. It adds IP address-to-location lookup capability to OpenSIPS scripts.

Lookups are executed against the freely-available GeoLite City database; and the non-free GeoIP City database is drop-in compatible. All lookup fields provided by the API are accessible by the script. Visit the MaxMind website for more information on the location databases.

The following modules must be loaded before this module:

  • No dependencies on other OpenSIPS modules.

The following libraries or applications must be installed before running OpenSIPS with this module loaded:

  • libGeoIP.

Path to either a GeoLite or GeoIP City database file.

Mandatory parameter.

Set 'mmgeoip_city_db_path' parameter
...
modparam("mmgeoip", "mmgeoip_city_db_path",
"/usr/share/GeoIP/GeoLiteCity.dat")
...

Looks up specified fields associated with IP address specified by the src. The resulting data are loaded in reverse order into the dst AVP.

src can be a pseudo-variable or AVP; and dst must be an AVP. fields defaults to “lon:lat,” and is a colon-delimited list of these elements:

  • lat Latitude
  • lon Longitude
  • cc Country Code
  • reg Region
  • city City
  • pc Postal Code
  • dma DMA Code
  • ac Area Code
  • TZ Time Zone

This function can be used from REQUEST_ROUTE, FAILURE_ROUTE, ONREPLY_ROUTE, BRANCH_ROUTE,ERROR_ROUTE, and LOCAL_ROUTE.

mmg_lookup usage
...
if(mmg_lookup("lon:lat",$si,$avp(lat_lon))) {
xlog("L_INFO","Source IP latitude:$(avp(lat_lon)[0])\n");
xlog("L_INFO","Source IP longitude:$(avp(lat_lon)[1])\n");
};
...

It is not currently possible to load an updated location database without first stalling the server.
