that file you get with wget is sort of schema definition, but doesn't have to be imported in mongo. Delete it, only Kamailio should insert into location table.

My steps:

1) wget https://raw.githubusercontent.com/kamailio/kamailio/master/utils/kamctl/mongodb/kamailio/location.json

2) [root@mongodb-1 root]# mongoimport --db test --collection location --file location.json -vvvv

Hello,

how was the record (json document) inserted in the location table? It doesn't seem to have valid values...

Cheers,
Daniel

Hello!

I want to keep user location in mongodb, but Kamailio does not start well.

Configuration:

loadmodule "usrloc.so"

loadmodule "db_mongodb.so"

modparam("usrloc", "db_insert_null", 1)

modparam("usrloc", "db_url", "mongodb://mongodb.test/kamailio")
