[OpenSIPS-Users] lcr- ideas?

[Bogdan-Andrei Iancu]

Hi Dmitri,

First of all, I would suggest to use the Dynamic Routing module for 
lcr-like purposes. The LCR module is old and does not scale as size and 
performance - anyhow, it will become obsolete in the next versions.
    See http://www.opensips.org/html/docs/modules/devel/drouting.html

How you can implement your system? - use in DR module the routing groups 
- you can group the routing rules (the prefixes) into different 
individual sets. When you invoke the routing function (from the script), 
you can specify the routing group you want to be use (see the parameter 
of the do_routing() function); see:
    http://www.opensips.org/html/docs/modules/devel/drouting.html#id272408
    http://www.opensips.org/html/docs/modules/devel/drouting.html#id227281

 From the script, based on whatever information (dialled number, caller 
profile, domain, etc) you can choose the routing group to be used . So 
you can have a single system with multiple sets of routing rules.

Regards,
Bogdan
