if I not yet received the BYE related with the INVITE (same sip_callid), I can suppose
with some margin error that this call is still alive....or i really wrong/forgot
something?? what I mean, if I polling in real-time the DB, I can fetch the real time
stats on ended calls, refused calls, missed-calls and live calls even if I know that SER
don't 'retain' the call state but maybe I can 'derive' this call state
from accounting/polling from/to DB.....or maybe the risk to not account the BYE message is
too high???
many thanks,
Verbal

How do you know the call is still alive? -jiri

Hi Jan,
thank you for your prompt replay....just an ultimate question about this topic..with the
avp_db module and/or avpops module and some external polling function on DB (query every 3
minutes (e.g.) that counts the INVITE method and sip_status (200) and not yet
disconnected (not yet received BYE) sorted by from HF)...if this count exceeds some limit
(settled per username@domain) stored in the avp table (simultaneous call limit), an
external script insert the hit username in the blocked ACL....does it make sense for you?
in case, which drawbacks do you see?
Best regards,
Verbal

No, that is not possible with SER.

http://lists.iptel.org/mailman/listinfo/serusers Hi all,
I have a very urgent question and I would know if anyone is dealing with
CAC on SER....exist any methods/function in statefull proxy mode to count
simultaneous calls coming from the same calling party number (from HF),
feeded from one IP PBX (like Asterisk) with just one single digest account
and one permitted uri, in case setting two call thresholds (one for the
allowed simoltaneous calls and one for the allowed call per second)? If
yes, is it possible blacklisting/barring this user (in a cached table with
function like file permission.deny) for some time/forever if the call counters
exceed limit settled by threshold?
10nx,
Verbal
