MultiDSLA

MultiDSLA is a measurement system for testing voice quality and assessing performance, from core technology development through network operations. It produces objective MOS scores using ITU-T PESQ and POLQA standards, and analyzes measures including delay, packet loss, jitter-buffer behavior, echo, speech and noise levels, codec distortion, VAD performance, call setup, and DTMF sequences. Its Controller can automate call setup and measurements on demand or on a schedule through a graphical network representation, while controlling more than 100 nodes. Nodes connect through legacy analog and handset interfaces, SIP/RTP networks, and mobile phones. Users can set pass/fail criteria for KPIs and monitor measures such as delay, jitter, MOS, echo, and speech levels. Field tests support fixed-line-to-mobile or mobile-to-mobile calls with GPS localization and synchronization and Google Earth mapping. The system offers access to online speech-to-text for functional testing or residential gateways, plus REST API and Python module support for automation integrations. The Controller supports specified Windows Server and desktop versions; its datasheet also lists smartphone call control through an Android app. Pricing is available on request.

MultiDSLA covers voice-quality measurement, node-based testing, and KPI monitoring. Teams should review its Windows requirements and request pricing for their intended setup.

MultiDSLA is aimed at device manufacturers, service providers, and telecom operators assessing voice quality or network performance. It may suit teams that need automated testing across connected nodes and configurable KPI criteria.

Overview

MultiDSLA is a voice-quality measurement and testing system for telecom engineering and network operations. It is best suited to manufacturers, service providers and operators that need to assess calls across many nodes; teams seeking a low-cost, self-serve monitor should look elsewhere.

Its appeal is the combination of standards-based voice scoring, broad call diagnostics and automated tests at scale. Custom pricing and a Windows-specific Controller requirement make it a more considered purchase than a lightweight monitoring tool.

Key features

MultiDSLA produces objective MOS scores using ITU-T PESQ and POLQA. It also analyzes one-way delay, packet loss, jitter-buffer behaviour, echo, speech and noise levels, codec distortion, VAD performance, call setup and DTMF sequences. That range is valuable when teams need to trace quality problems beyond a headline score, including signalling and media behaviour.

The Controller can schedule call setup and measurements or run them on demand, using a graphical network representation. It controls 100+ nodes, a strong fit for complex test processes but likely more capacity than a small deployment needs. Nodes can connect through legacy analog and handset interfaces, SIP/RTP networks, and mobile phones, accommodating mixed endpoint environments.

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

REST API and Python module support let teams integrate MultiDSLA with quality-test automation software such as HP Quality Center. VoxPort Packet supports SIP over TLS and secured RTP. These capabilities help fit the product into established testing and secure voice environments, though they are most relevant to teams with integration and telecom-testing needs.

Pricing

MultiDSLA is paid software with custom pricing. The MultiDSLA plan includes the Controller plus one or more node devices and controls 100+ nodes; teams should request pricing for their intended setup. There is no published free tier or trial to evaluate before committing, so buyers should clarify the cost and scope for their required node configuration.

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 lists smartphone call control through an Android app. The Windows requirement is a practical constraint for teams whose testing environment is built around other operating systems.

Who it's for

MultiDSLA fits device manufacturers, service providers and telecom operators that need repeatable voice-quality measurements across legacy, IP and mobile connections. Its 100+ node capacity, KPI criteria and automation support larger or more intricate testing and SLA workflows. A small team looking mainly for basic monitoring, a free option or broader desktop platform flexibility is better served by another tool.

Pros and cons

Pros

• Detailed voice diagnostics: MOS scoring is complemented by analysis of delay, loss, jitter, echo, codecs, VAD and call signalling.
• Scale and automation: Scheduled or on-demand tests can control 100+ nodes, supporting complex test processes.
• Mixed-network coverage: Analog, handset, SIP/RTP and mobile connections support testing across different voice paths.
• Operational integrations: REST API and Python support, KPI pass/fail criteria, and field-test mapping extend its use beyond basic scoring.

Cons

• Custom pricing: Buyers must request a quote, and there is no published free plan or trial.
• Windows-specific Controller support: The supported Windows versions may not suit teams standardizing on other operating systems.
• Potentially excessive scale: Control of 100+ nodes is useful for complex deployments but may be unnecessary for small teams.

Alternatives

Obkio is worth considering for teams that want a freemium option, a 14-day Premium-feature trial capped at 10 agents, or wider platform support including iOS, Linux and macOS. Its free plan is also available, while MultiDSLA emphasizes voice-specific scoring and multi-node testing.

Dotcom-Monitor may fit teams looking for a free plan: it covers up to 25 targets, monitors as often as every five minutes, and includes two monitoring locations and email alerts. MultiDSLA is the more voice-testing-focused choice based on its MOS, call-quality and node capabilities.

Telchemy SQmediator is another paid option for buyers comparing voice-quality monitoring systems; its Small Service Provider Edition is single-server, with optional Web Services API and passive plus active monitoring at additional cost.

sip-exporter is a free, self-hosted Linux option under AGPL-3.0, with conditions for commercial use. HOMER is a free, open-source choice with commercial support available by quote. Teams evaluating either should weigh those licensing and deployment models against MultiDSLA's node-based voice testing.

Bicom Systems SIP Monitoring (sipMON), CallMeter and Nectar Diagnostics are additional alternatives to consider.

Verdict

MultiDSLA is a strong fit for telecom teams that need standards-based MOS scoring, detailed call diagnostics and automated tests across large or mixed networks. Its main reason to choose it is the combination of 100+ node control and broad voice-quality analysis; its main reason to look elsewhere is the custom-priced, Windows-dependent Controller, particularly for small teams or buyers who need a free starting point.
