Hi everybody,

Following the past discussion about the enhancing the routing 
capabilities of OpenSIPS (see 
http://lists.opensips.org/pipermail/users/2008-August/000343.html), a 
new module was uploaded - Drouting (Dynamic Routing).

This module is  similar to LCR (as basic functionality - routing based 
on rules and GWs) , but has a different (scalable and performance - see 
design and some enhancements.

Technical adds:
    - internal data organized as a search tree - very fast to search 
through ( O(log(n)) instead of O(n) )
    - unlimited number of rules and gateways (running on a production 
setup with 200K rules and with no search penalties)
    - rule matching may include time intervals and recurrence (when the 
rule is valid)
    - a rule may point to set of GWs to be used for (1) sequential 
selection, (2) random selection , (3) weight selection
    - inbound processing - prefix and strip for calls originated by the GWs

As said, this module is almost 3 years old and stable - it is what we use in our 
production setups.
Also, the module already has a nice web interface for provisioning (it 
will released in the next weeks, along with an OpenSIPs Control Panel 
Web interface).

A comprehensive documentation is available on site :

Any comments are welcome.
