Best of New in Kamailio 3.0.0 - #13: number portability

Contributed by 1&1, the German provider running a telephony service with over 3 000 000 subscribers, Kamaialio (OpenSER) 3.0.0 comes with a suite of tools to implement fast number portability handling:

• pdbt server - located in source directory, under utils/pdbt
• pdb module - client for the server, as Kamailio module

The PDB module and server have support for load-balancing and aggressive timeouts (in milliseconds), offering a scalable framework for number portability service.

The module can query in many servers in parallel and use the first answer , ensuring just few milliseconds to query the remote server and return the reply to the configuration script. Runtime management can be done via Kamailio's control interface (e.g., via XMLRPC, FIFO file, UDP or TCP sockets).
