<div>5. Rounding (In short duration calls, customers tend to consider 3.1 seconds as 3 seconds while providers tend to consider 4 seconds (have a pre-agreement with the customer, use microseconds timestamps to decide). </div>

I'm relatively new to OpenSIPS but have been able to deploy a few OpenSIPS<br>
installations at our organisation with the assistance of some experts.<br>
<br>
Our environment is of terminating short-duration calls for call-centers<br>
predominantly. In such a case, we haven't been receiving accurate billing<br>
CDRs as the CDRs being generated by the platform have durations that are<br>
inflated by 40-60%.<br>
<br>
It was suggested by someone to enable in-call pings and proxy media which<br>
have also implemented and whilst this has improved the discrepancies it<br>
hasn't fully resolved them.<br>
<br>
Any tips would be greatly appreciated.<br>
<br>
Thanks,<br>
Sahil<br>
<br>
