Wireless End to End: IMS/ LTE Networks (VOLTE, VOIP, femtocells, big data)

This webinar explores VoLTE specific service verification and trouble-ticket examples. The main focus is on end-to-end VoLTE session detection, problem identification and root cause analysis.

Examples are given on how to analyze VoLTE issues in live networks with a passive analyzer. This webinar is meant for operations engineers with a background in LTE and moving towards VoLTE deployment, as well as field teams optimizing and troubleshooting VoLTE services.
