Description:Adds call duration and billsec in floating type which gives exact time, not rounded as default CDR implementation.

This functionality is essential to bill calls correctly.

****** ADDITIONAL INFORMATION ******

Currently ${CDR(duration)} and ${CDR(billsec)} are rounded to nearest integer.

This is not acceptable for most billing issues.

Patch adds ${CDR(rduration)} and ${CDR(rbillsec)} which looks like this:

exten => h,n,NoOp(Real duration: ${CDR(rduration)})
exten => h,n,NoOp(Real billsec: ${CDR(rbillsec)})

   -- Executing [h@context:6] NoOp("SIP/1003-00000000", "Real duration: 9.165070") in new stack
   -- Executing [h@context:7] NoOp("SIP/1003-00000000", "Real billsec: 4.067524") in new stack

You need to submit new features patches against the SVN trunk version.

Most, if not all, legacy PABXes only log durations to a second, and many of them only log start times to a minute, so I think that saying it is not acceptable in most cases is an overstatement, although, as a pure new feature, it is harmless.

There is some risk from the excessive accuracy.  The two sides of a SIP connection could disgree by 100s of milliseconds as to when the call started or ended.  Actually it could be many seconds if the nominal final packet was lost.

This is a new feature, so we won't be putting it in 1.4.

For trunk, someone has a patch for doing something like this already. See this code review:
