[OpenSIPS-Users] radius keep alive (Accounting Interim Update)

[Ewgeny]

Hi!

I use Opensips 1.9 with RADIUS accounting functions - "radius_send_auth" 
and  "radius_send_acct" (AAA RADIUS MODULE).
Now I want to make a more reliable RADIUS accounting by sending 
periodically RADIUS packets - Interim Update (or RADIUS keep-alive).
Ie Keep-alive packet to be sent every 10 seconds, provided that the 
active SIP dialog.
Tell me how to do it?
In which route or what function it is possible to carry out periodical 
actions?
