Do you have SIP traces for the call? If you're bridging then it's possible for the remote end to hangup the answered call with an ISDN clearing cause other than NORMAL_* (just like they can in ISDN signalling). For billing purposes I suggest you bill anything where billsec>0 rather than only NORMAL_CLEARING calls. -Steve On 4 September 2012 19:23, Muhammad Naseer Bhatti <nbhatti@gmail.com> wrote:
Hi, I am seeing a lot of calls with hangup cause/Enumeration is not NORMAL_CLEARING while the calls still have a valid duration and answered time. For a typical billing scenario, calls are billed if (answered time) billsec>0 and hangup cause = NORMAL_CLEARING. In what cases the enumeration would be other than normal and while the calls would be still a valid answered call?
Thanks
