CUCM CDR Call Duration Field

Hi there,

 

We are planning to use CDR data on CUCM for billing purposes. During our initial testing, we have identified the Call Duration shown on CDR is slightly innacurate: as soon as the FXO port connects, the call is considered to be running and the timer starts counting, even if we only here the ringing tone.

 

As a result, we are getting calls with 15-20 sec duration where there was no call established, hence these are calls we shouldn´t count for billing.

The question would be: is there any parameter either on CDR/CUCM or the Gateway, that can help to correct this timing innacuracy? How do you guys overcome this timing difference when you set up a billing system?

 

Comments are welcome!
