Hi Tamas,

I guess you are using an version older than 1.1.x of openser - starting with 1.1.0, the e2e ACKs do have a distinct branch (and not 0 as prior).

but anyhow, the ACK acc should work - maybe the ACK received by openser does not match the INVITE, so it is not accounted. try to run in debug mode to see if the ACK match the INVITE. Look for something like:

DEBUG: t_lookup_request: e2e proxy ACK found

regards, bogdan

Hello,

I'd like to relay sip calls from openserto another sip proxy (asterisk), and i have a problem with radius accounting, i 'd like to report acks, but openser doesn't send accounting packet on it. As i understand ack requests must match a transaction flaged to accounting.

Config look like this, so i think all transaction is flaged.

modparam("acc", "report_ack", 1) modparam("acc", "radius_flag", 1) modparam("acc", "radius_missed_flag", 2)

route{ ... setflag(1); setflag(2); ... }

Asterisk retransmit the 200 ok, so i think there is something mistake in the ack. as i read in rfc 3261, ACK must match the dialog, callid, from, to, fromtag, to, tag, and sequence number is relevant. and ack on a 200 ok, is always a new transaction, however i see branch parameter is 0 in the ack, it must start with the magic cookie z9hG4..., isn't it?

I dont understand what could be the problem, why 200 ok is retransmitted, and why not openser send acctpacket to radius.

Please someone take a look at the sip messages
