[OpenSIPS-Users] How to change From user before do_routing?

[Bogdan-Andrei Iancu]

Hi Kirill,

Well, internally, the drouting module is also doing a query to DB , to 
the dr_group table (there is no cache here) -> so, it is the same, when 
comes to performance. Or you can keep the per-user routing group in the 
subscriber table and have it loaded during authentication (see the 
load_credential parameter).

And again, the dr_groups is not cached, it is a real time query to DB 
;). Only the rules/carriers/gateways are cached, but not the groups.

Regards,

Bogdan-Andrei Iancu
