Commit to quality voice services every time, real-time

Voice technologies and the cost of voice have changed over time. Voice over IP (VoIP), Voice over LTE (VoLTE) and Voice over WiFi (VoWiFi) are cost-effective ways to transport voice. Regardless of the technology and the path from one end to the other, customers’ expectations on quality remain high. New voice codecs, such as EVS and the competition from OTT voice services, warrant increased attention to voice quality.

Mobileum’s Voice Testing Solution monitors the performance of voice services across all technologies, services, and codecs. Our Active Testing Platform monitors voice quality using industry standard algorithms (POLQA), and generates real-time insights and alarms for:
  • Fixed Line (PSTN and ISDN)
  • 2G & 3G Circuit Switched Voice
  • Voice over LTE (VoLTE)
  • Voice over WiFi (VoWiFi)
  • Voice over IP (VoIP)
  • Circuit Switched Fallback (CSFB)
