Create a geopoint database

Hi,

I would like to use a map like with geoip toshow the source or destination of call on a map.

I' don't know if it exist already a database of geopoint based on the first digits of a international phone number.

If that database does not exist is it possible to create one by myself ( should be a long job ..) ?
If i have to creat one by myself could you help me how to do it ?

Thx

I'm not sure if such a thing already exists, but I think this question would be better answered in the Logstash forums, where they might be able to help you enrich your data to include not only the phone number, but a geoip associated with the area code of the phone number.
