The VOIPFUTURE call correlation process matches VoIP signaling sessions with the media streams belonging to the session and essentially attaches a subscriber ID to call quality. The patent pending correlation mechanism matches multiple media streams including those from early media, like ring tones or tariff announcements, codec changes and network address translation (NAT) impaired sources to the correct signaling session.
The resulting xDRs contain unmitigated information on the call quality on a per direction basis with a 5 second granularity with full subscriber details – unrivaled in the VoIP monitoring/voice assurance market.
The correlation engine is designed to work in decomposed environments such as IMS and LTE where network equipment may be spread across multiple geographical locations. stated Michael Krueger, Head of Research and Development of VOIPFUTURE. He added With our updated solution you are able to monitor, document and evaluate VoIP calls on a new level.
The challenge of any voice quality SLA is to match voice media quality with phone numbers. Phone numbers, subscriber IDs, routes, destination etc. are the common data for service contracts. As voice media is transported independent from the signaling data, these data is not easily available but crucial. Dr. Michael Wallbaum, Director of Product Marketing at VOIPFUTURE said Service providers can now implement and enforce media quality service level agreements based on signaling information like SIP trunks, customers or numbering plan entries.
