When you are monitoring a VoIP traffic, CDR (Call Detail Record) screen is one of your best friends, helping you by showing what’s going on! You can track the rates and changes and make inferences about the traffic and routes.
Today we are going to mention this screen in detail and try to tell the benefits of the CDR. Let’s start, today is the day for meeting your helpful friend.
What is CDR?
CDR stands for Call Detail Record and helps us to see everything about incoming calls. The number of the caller and called ones, time of the call, errors, if it is a successful call; call duration, the side that ends the call… All these pieces of information and more is visible on CDR screen. In other words, CDR screen is an ID card of a call that has every bit of information.

The things that we can monitor from CDR screen
Call Detail Record screen is important because most of the time we determine the SIP Codes from here and take action immediately.
An example for the CDR screen usage for determining SIP-503 Service Unavailable
Sip 503 means no service at that time. You can understand this code from ASR rates. If it starts to decrease dramatically then we can get this code. Cut before everything we need to analyze the CDR of the traffic. We need to examine the % rate of the 503 code on CDR and compare it with the past.
