Concurrent Calls

There are several changes in this version:

• Fixed a serious bug in the calculation of the number of calls and the duration of time spent on each call.
• Added the ability to filter calls based on trunk in addition to the source or destination number.
• Made call filtering more restrictive. Now, in order for a call to be included in the reports, it needs to have billsec > 0 as well as duration > 0.
• This version now uses the full duration of the call for its calculations instead of just the billable duration of the call.
• Changed the display of total minutes used from a decimal to MM:SS format.

I want to thank Bart for tracking down the major bug, which is fixed in this release, in addition to providing his CDRs which aided in this release.
