peter,
you suggested to use accounting stop request for failed sip requests. that is not a good idea, because what didn't start cannot stop either.
in other words, my stop records contain only a small number of attributes enough to match the start record that holds many more attributes. in case of failed request, i don't have a corresponding start record, but i do need all the same attributes in failed request that i have in start request.
Hi Juha The amount of attributes that your (I guess you mean openser) stop records _currently_ contain have nothing to do with the issue at all. (Most NAS infact put much MORE info into the Stop records than the Start ones as that is typically the record you use for billing) My suggestion was to simply have the Failed records be of Acct-Status-Type "Stop". The RFC does not state that there has to be a Start record in order for there to be a Stop record and this is how most vendors do it. (If you wish to add an extra attribute that includes the word "Failed" then by all means do so..) Here is an example Start and Stop record from a Cisco 53XX series running H.323 (Sorry don't have any production SIP installations at present) Please take note of "Cisco-AVPair" attributes which may contain arbitary data (according the Cisco's dictionary) and the length of the records Sat Oct 16 06:38:54 2006 Acct-Session-Id = "00BA5EC6" h323-setup-time = "16:36:05.023 GMT+2 Sat Oct 16 2006" h323-gw-id = "gw1-5300." h323-conf-id = "A6C16E86 205211D9 87870003 BA6B5AFA" h323-call-origin = "originate" h323-call-type = "Telephony" Cisco-AVPair = "h323-incoming-conf-id=A6C16E86 205211D9 87870003 BA6B5AFA" Cisco-AVPair = "subscriber=Unknown" Cisco-AVPair = "out-intrfc-desc=" Cisco-AVPair = "gw-rxd-cdn=ton:0,npi:0,#:696990535792987" User-Name = "195.2.2.1" Acct-Status-Type = Start NAS-Port-Type = Async Cisco-NAS-Port = "ISDN 1:D:1" NAS-Port = 0 Called-Station-Id = "696990535792987" Service-Type = Login-User NAS-IP-Address = 212.1.1.1 Acct-Delay-Time = 5 Client-IP-Address = 212.1.1.1 Acct-Unique-Session-Id = "0657b177760ba193" Sat Oct 16 06:38:55 2006 Acct-Session-Id = "00BA5EC6" h323-setup-time = "16:36:05.023 GMT+2 Sat Oct 16 2006" h323-gw-id = "gw1-5300." h323-conf-id = "A6C16E86 205211D9 87870003 BA6B5AFA" h323-call-origin = "originate" h323-call-type = "Telephony" Cisco-AVPair = "h323-incoming-conf-id=A6C16E86 205211D9 87870003 BA6B5AFA" Cisco-AVPair = "subscriber=Unknown" Cisco-AVPair = "out-intrfc-desc=" Cisco-AVPair = "gw-rxd-cdn=ton:0,npi:0,#:696990535792213" Acct-Input-Octets = 440 Acct-Output-Octets = 0 Acct-Input-Packets = 22 Acct-Output-Packets = 0 Acct-Session-Time = 0 h323-connect-time = "16:36:05.675 GMT+2 Sat Oct 16 2006" h323-disconnect-time = "16:36:05.675 GMT+2 Sat Oct 16 2006" h323-disconnect-cause = "1C" Cisco-AVPair = "h323-ivr-out=Tariff:Unknown" Cisco-AVPair = "release-source=3" h323-voice-quality = "0" Cisco-AVPair = "gw-final-xlated-cdn=ton:0,npi:0,#:05357111111" Cisco-AVPair = "charged-units=0" Cisco-AVPair = "disconnect-text=invalid number (28)" Cisco-AVPair = "peer-address=696990535792987" Cisco-AVPair = "info-type=speech" Cisco-AVPair = "peer-id=69691" Cisco-AVPair = "peer-if-index=280" Cisco-AVPair = "logical-if-index=105" Cisco-AVPair = "acom-level=20" Cisco-AVPair = "coder-type-rate=g729r8" Cisco-AVPair = "noise-level=0" Cisco-AVPair = "voice-tx-duration=0 ms" Cisco-AVPair = "tx-duration=0 ms" User-Name = "195.2.2.2" Acct-Status-Type = Stop NAS-Port-Type = Async Cisco-NAS-Port = "ISDN 1:D:1" NAS-Port = 0 Called-Station-Id = "696990535792987" Service-Type = Login-User NAS-IP-Address = 212.1.1.1 Acct-Delay-Time = 5 Client-IP-Address = 212.1.1.1 Acct-Unique-Session-Id = "0657b177760ba193" Cheers -- Peter Nixon http://www.peternixon.net/ PGP Key: http://www.peternixon.net/public.asc
