A system for monitoring calls in a VoLTE network is provided. The monitored calls include SIP, RTP and H.248 portions. The system includes monitoring probes and first and second correlation engine components (CECs). The probe is configured to generate SIP, RTP and H.248 data records (DRs), send the SIP DRs to a second CEC based on a distribution key, generate and send a routing label to a first CEC and to send the H.248 and RTP DRs to the first CEC based on the first and second attributes, respectively. The first CEC is configured to correlate the received RTP and H.248 DRs and the routing label based on the second and first attributes, respectively, and send the correlated DRs to the second CEC based on a distribution key. The second CEC is configured to bind all of the generated DRs to a single call based on the distribution key.
