Hi,

I am searching for a setup where phones register at a central kamailio and kamailio shares these contact infos with multiple asterisks.

So they all need to share a database. For redundancy reasons, the database should work across 2 datacenters.

As far as 1 understood there are some options

• use mysql - good chances to find example code, Siremis API, seems to be the standard solution
  
• use redis - more performant than mysql
  
• use ldap - good chances to integrate with existing IT management but most difficult to configure
  

Kind regards,

Volker
