SITE for QoS & QoE

Network Service Performance - Voice Testing

Get best-in-class mobile voice quality across 2G, 3G, 4G, LTE and VoWiFI technologies with SITE Voice Testing and analysis.

About SITE Voice Testing

How many mobile customers are you losing every month due to poor call quality? Up to 30 percent of all mobile customers abandon their mobile carrier due to inadequate voice quality. 

To prevent your customers from switching to alternative OTT voice services such as Skype or WhatsApp, SITE helps you monitor voice quality 24/7 across all network technologies, services and codecs providing standard voice quality measurements using the POLQA algorithm.

Voice Testing Services

SITE voice testing works to ensure that your call quality exceeds industry standards with:

  • Voice Over LTE (VoLTE): Monitor, assure and validate the configuration for all network nodes (such as LTE/EPC/IMS) with end-to-end VoLTE (IR.92) testing. SITE test cases support IMS registration, VoLTE to VoLTE, VoLTE MO/MT to legacy networks (2G/3G/PSTN), VoLTE Supplementary Services and more.
  • Video Over LTE (ViLTE): Ensure quality of service by testing with Video over LTE. SITE test cases let users send audio and video reference files, measure audio and video quality and test SIP and RTP performance. MOS measurements are provided with the industry standard PEVQ algorithm.
  • Voice Over WiFi (VoWiFI): In order to monitor, assure and validate the configuration for all network nodes including LTE/EPC/IMS, it’s vital to test VoWiFi from an end-to-end perspective. SITE test cases support various scenarios IMS registration, VoWiFi to VoWiFi, VoWiFi to VoLTE and to legacy networks (2G/3G/PSTN) and also VoWiFi Supplementary Services.
  • Circuit Switched Fallback (CSFB): Because the introduction of LTE for data services is still in its initial stage, the need for voice calls to fall back into 3G or 2G technology has created a range of new network challenges. CSFB ensures that your subscribers can continue to make seamless voice calls until LTE is rolled out nationally.
  • 2G/3G/3G HD Voice: SITE test cases assure that your existing CS-based voice services work at the highest level when your network migrates towards new technologies such as VoLTE.
