PBX CDR vs Snom CDR

Recommended Posts

We are using Snom phones on our PBX system and I was trying to figure out why the CDR from the Snom phone and the pbxnsip system don’t match. What’s happening is every time the PBX receives a call it automatically starts its CDR counter even though the call has not been answered. The Snom Phone only stars its CDR once you answer the call. There has been some cases where in the Snom phone has a 1 sec missed call of its CDR but on the PBX its recorded as a 30 sec call. And that is what is causing the CDR difference. I already tried making those extension as an Agent Group and a Hunt Group but the result is still the same. Question is how can I make the PBX system only start’s its CDR once you pickup the call or when it goes in a voice mail

 

Thanks

The PBXNSIP CDR has two timing elements to be concerned with. Time Start and Time Connected.

The Time Start is obviously when the call began.

The Time Connect is when the call is actually answered.

This works well for Supervised Trunks (T1 PRI & SIP Trunks).

Not so well for PSTN (Telephone Line) Gateways

 

This may explain some of the time differences you see.

 

Also, where is the PBXNSIP getting its time of day from?

Is it the same for the Snom phone?

Or did you set the time on the Snom phone locally through the phone itself?

 

It would be best if they both went to the same source to eliminate any differences.

 

Hope this helps a little.

========================================================

The PBX and Snom phones gets their time on the same location. And we use SIP trunks. One thing i notice on the PBX CDR is that the TS and TC is always equal on ACD calls only

 

Thanks
