1. According to our Billing system ABC account have 180 seconds left.
2. Billing system passed to Cisco GW the following attributes in the authorization response:
-----------------------------------------------
h323-ivr-in = DURATION:180
h323-return-code = 0
h323-currency = SGD
h323-credit-time = 180
-----------------------------------------------
3. Based on this information Cisco GW should disconnect the call (please note that in this case Cisco managed the call disconnection).
4. After the call ended Billing received the following attributes in the Stop Accounting request from Cisco GW:
-----------------------------------------------
NAS-IP-Address = 'x.x.x.x'
User-Name = '5555657466'
Called-Station-Id = '60379806579'
Calling-Station-Id = '65601865'
Acct-Status-Type = 'Stop'
h323-call-origin = 'originate'
h323-setup-time = '10:44:29.469 cct Wed Mar 10 2010'
h323-connect-time = '10:44:40.511 cct Wed Mar 10 2010'
h323-disconnect-time = '10:47:40.522 cct Wed Mar 10 2010'
h323-disconnect-cause = '10'
Acct-Session-Time = '180'
-----------------------------------------------
Acct-Session-Time = h323-disconnect-time - h323-connect-time
Acct-Session-Time = 10:44:40.511 - 10:47:40.522
Acct-Session-Time = 180.011 seconds
From the Cisco GW side the call was considered as 180 seconds, but our billing system computed call duration as (h323-disconnect-time - h323-connect-time) and received value rounded to 181 seconds.
Is there a way that Cisco GW will disconnect the call at exactly 180 seconds or less?
