MultiDSLA vs VoIPmonitor

MultiDSLA is a measurement system for voice quality testing and performance assessment, spanning core technology development through network operations. It produces objective MOS scores based on ITU-T PESQ and POLQA standards, alongside measures for one-way delay, packet loss, jitter-buffer behavior, echo, speech and noise levels, codec distortion, VAD performance, call setup, and DTMF sequences. Its Controller automates call setup and measurements on demand or on a schedule through a graphical network representation, controlling more than 100 nodes. Nodes connect through analog and handset interfaces, SIP/RTP networks, and mobile phones. Users can define KPI pass/fail criteria and monitor measures such as delay, jitter, MOS, echo, and speech levels. Field testing supports fixed-line-to-mobile or mobile-to-mobile calls with GPS localization and synchronization and Google Earth mapping. The system offers online speech-to-text access and 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.

VoIPmonitor is an open-source packet sniffer paired with a commercial web GUI for monitoring, troubleshooting, and recording VoIP and RTC calls. It reports MOS, jitter, packet loss, delay, and RTCP data. Recording includes calls and SIPREC sessions, with policy-based retention and deletion rules. Troubleshooting tools provide packet captures, SIP ladder diagrams, audio waveforms, spectral analysis, and TLS/SRTP decryption. The GUI adds dashboards, OLAP analytics, scheduled reports, KPI alerts, and fraud-detection rules. Listed compatibility includes Kamailio, OpenSIPS, FreeSWITCH, Asterisk, Cisco, Avaya, Genesys, Mitel, AudioCodes, Ribbon, and Oracle SBC. Supported protocols include SIP, RTP, RTCP, SIPREC, SKINNY, MGCP, SS7, SCTP, WebRTC, Diameter, TCP, SSL, and TLS. The sniffer runs as a static Linux binary with x86 and ARM builds. Cloud CDR retention is 21 days, PCAP remains on the customer server, and the listed maximum is 2,000 channels. Cloud 3 channels costs $22 a month; On-Premise 10 channels costs $45 a month.
