How to know a fax call or voice call ?

[npthai]

Hello !

I'm using ACS to collect the CDR for my VoIP network. I need to know the call is fax or voice but the ACS does not has any field to show that.

Could any one help me.

Many thanks.

I don’t think debug radius shows different attributes or values for a fax call vs. a voice calls so I don’t think you’ll be able to differentiate between the two.
