MultiDSLA

Overview

MultiDSLA is a voice-quality measurement system for telecom engineering and network operations teams that need to assess calls across different kinds of endpoints. Its mix of standards-based MOS scoring, automated test runs and control of more than 100 nodes makes it a strong fit for complex voice environments, though it is a paid system with custom pricing.

Key features

Objective MOS scores use ITU-T PESQ and POLQA, giving teams recognized measures of perceived voice quality. The analysis goes beyond a single score: it covers delay, packet loss, jitter-buffer behaviour, echo, speech and noise levels, codec distortion, VAD performance, call setup and DTMF sequences. That breadth is useful when diagnosing call-quality problems across both media and signalling behaviour.

The Controller can schedule measurements or run them on demand, using a graphical representation of the network to automate call setup and tests. It can control 100+ nodes, a meaningful advantage for large or intricate test processes, but likely more capability than a small team needs. Nodes can connect through legacy analog and handset interfaces, SIP/RTP networks or mobile phones, helping teams assess mixed or evolving telecom environments.

Teams can set KPI pass/fail criteria and monitor delay, jitter, MOS, echo and speech levels for SLA management. Field testing supports simultaneous fixed-line-to-mobile or mobile-to-mobile calls, with GPS localization and synchronization and Google Earth mapping. Automatic access to an online Speech-to-Text platform adds functional testing for residential gateways.

REST API and Python module support make it possible to integrate measurements into quality-test automation software such as HP Quality Center. The VoxPort Packet component supports SIP over TLS and secured RTP. These capabilities suit teams connecting voice testing with broader workflows, while the product’s focus remains specialized measurement rather than a general-purpose monitoring tool.

Pricing

MultiDSLA is paid, with custom pricing. The MultiDSLA plan consists of the Controller plus one or more node devices and supports control of 100+ nodes. That structure suits organizations that need a configurable node deployment, but gives smaller teams no published entry price to compare against their requirements. No free plan or trial is included in the plan information.

Platforms

The Controller supports 32-bit and 64-bit Windows Server 2012 R2, Windows Server 2016, Windows 7 Professional SP1 and Windows 10 Pro. The Controller datasheet also describes smartphone call control through an Android app. The product is categorized for Android, API, web and Windows, but the Controller’s operating-system support is specifically Windows; organizations should confirm that this fits their intended deployment.

Who it's for

MultiDSLA is aimed at device manufacturers, service providers and telecom operators working on voice quality from core technology development through network operations. It is especially relevant where teams need repeatable multi-node testing, standards-based voice scores, or test coverage spanning analog, SIP/RTP and mobile connections. Organizations seeking a lightweight, low-cost monitoring service or a deployment that avoids Windows should consider other options.

Pros and cons

• Pros: PESQ- and POLQA-based MOS scoring sits alongside detailed media and call-behaviour analytics, supporting diagnosis beyond a headline quality score.
• Pros: Scheduled and on-demand automation across 100+ nodes can support complex test processes at scale.
• Pros: Analog, handset, SIP/RTP and mobile connectivity gives teams options for mixed endpoint testing, with GPS-linked field-call support.
• Cons: Custom pricing makes it harder to judge affordability before engaging with the vendor.
• Cons: The Controller’s supported operating systems are Windows versions, which can rule it out for teams requiring a Linux-based controller.
• Cons: The 100+ node capacity and broad telecom testing focus may exceed the needs of teams looking for basic voice monitoring.

Verdict

Choose MultiDSLA if you are a telecom operator, service provider or device maker that needs standards-based voice scoring and automated testing across many nodes and connection types. Its chief strength is combining detailed call-quality analysis with flexible test automation. Look elsewhere if you need a free or transparently priced entry point, or if Windows support does not suit your deployment.
