VoIP & Microsoft Unified Communications (UC) monitoring and benchmarking platform
Successful Voice over IP (VoIP) and Microsoft Unified Communications (using windows live media) implementations adopt a customer-focused operational model that offers sustainable and measurable customer experience at all times. Traditional performance monitoring tools are network focused and take an inside-out approach by measuring throughput, packet loss, jitter and latency evident within the network core. However, network-related issues do not entirely represent the true end-user experience as the majority of IP Communications problems evident beyond the network edge are not available. To achieve competitive differentiation, retain high-value customers, and drive growth, service providers today must recognize the need to truly understand end-user Quality of Experience.
Epitiro now offers a fully-automated and managed VoIP Quality test, reporting & benchmarking system and supports a wide variety of call scenarions including:
-
Session Initiation Protocol (SIP)
- VoIP to VoIP
- VoIP to Windows Live Media
- VoIP to PSTN
- VoIP to Mobile
-
Microsoft Unified Communiation Platform - Windows Live Media (WLM)
- WLM calls terminating on Windows Live Media (using MS unified codec pack)
- WLM calls terminating on PSTN
- WLM calls terminating on VoIP
- WLM calls terminating on Mobile Handsets (National / International)
- Public Switched Telephony Network (PSTN)

- PSTN calls terminating on Mobile handset
- Mobile/Cellular Network
- Mobile calls terminating on PSTN
- Mobile calls terminating on Windows Live Media
- Mobile calls terminating on VoIP
- Mobile calls terminating on Mobile
ISP-I for Voice provides continuous, real-time visibility of the health and status of the Key elements of your IP Telephony infrastructure and MOS-based quality reports of test voice calls from a single, unified Interface. The ISP-I platform provides monitoring and reporting across any call-path (IP, TDM, Mobile/Wireless handset termination) or mix of PBX or IP-PBX platforms and provides a real-time consolidated view into the QoS/performance of all call-types applicable in your environment.
Active testing agents provide on-going link quality and performance measurements for VoIP services by intitiating calls between agents & pre-defined termination points anywhere inside or outside the network. These automated test schedules are an important component of real proactive monitoring and testing, as they enable benchmarking of voice service quality, and detect degradation before end users do. The reporting module provides availability and voice quality (MOS / PESQ) measurements on every test call session. All data is reported and available in real-time through the online ISP-I portal:
Measuring Voice Quality using PESQ - How ISP-I (VoIP) Works
PESQ measures one-way voice quality: a signal is injected into the system under test, and the degraded output is compared by PESQ
with the input (reference) signal. The test signals must be speech-like because many systems are optimized for speech and respond
in an unrepresentative way to non-speech signals (e.g. tones, noise, ITU-T P.50).
ISP-I for Voice will objectively determine voice quality from the all-important subscriber perspective. The system uses standards-based Perceptual Evaluation of Speech Quality (PESQ ITU P.862) to provide an automated, MOS-based objective voice quality score. The VoIP module can objectively determine voice quality from the subscriber's perspective. Agents use a standards-based Perceptual Evaluation of Speech Quality (PESQ ITU P.862) to provide an automated, MOS-based objective voice quality score.
The VoIP analyser measures end-to-end speech quality in both directions and is specifically designed for use with intrusive tests. Once a call is initiated, an voice sample is passed through the network under test and the degraded output is compared with the input (reference) signal. The Voice signal may be sampled at 8kHz or 16kHz.
