h1. Сompare CDR

{{>toc}}

This tool enables you to perform [[CDR comparison]].

Following parameters are compared:

* B-number (callee ID)
* duration
* price

Call start time is solely informational.
It's not being compared, because there are possible differences in time zone and time synchronization settings between your and peer's systems.
However, call start time is displayed in comparison results in order to identify the call.

Below are the steps needed to perform CDR comparison.

h2. Import file with CDR, which you got from peer

Configuring import options is the same as in all other file import menus in Smartswitch.

h2. Choose parameters for CDR selection from Smartswitch's database

!compare_cdr2.gif!

*from* - from which time to select CDR from Smartswitch's database
*to*- to which time to select CDR from Smartswitch's database
*peer's time zone* - check this to specify in *from* and *to* values in peer's time zone.
For this to work, you need to specify time zone in [[Companies|Company]] settings.
*direction* - inbound or outbound CDR to select from Smartswitch's database
*sorting* - should better match with sorting used in CDR file that you've got from peer.
*match number* - choose *callee id*, if peer specified B-number without prefix in his CDR file.
Choose *real callee ID*, if peer specified B-number with prefix in his CDR file.
*answered only* - check, if you want to compare only answered calls.

h2. Set difference criteria

*answered duration difference (sec)* - in case if difference of answered duration between Smartswitch's CDR and peer's CDR is less or equal than specified value, it's considered that there is no duration difference
*price difference (currency)* - in case if difference of price between Smartswitch's CDR and peer's CDR is less or equal than specified value, it's considered that there is no price difference
*show differences*:
* *system* - show CDRs, which are present in Smartswitch's DB, but are absent or differ in peer's CDR file
* *imported* - show CDRs, which are present in peer's CDR file, but are absent or differ in Smartswitch's DB

h2. List differences

!compare_cdr4.gif!

CDRs with differences are displayed.
NULL is displayed for calls with are absent.

Press *Export* to export differences to a file.
This file could be sent to peer to continue dispute resolution.
