Hi,

Thx for prompt answer.
I was playing around with lcr table and found that i may place an IP
address which is a part of sip uri there.
It means that if a call is originated from 77.77.77.77 (from sip uri
482223344 at 77.77.77.77) then grp_id=3 should be chosen.
Of course i may wipe this out but i am unsure if it help.

Thx,
Maciej
