Bicom Systems SIP Monitoring (sipMON) vs MultiDSLA

Bicom Systems SIP Monitoring (sipMON) is a Linux, self-hosted tool for ITSPs and PBXware environments. It captures SIP signaling and RTP traffic, tracks calls, and stores call-detail records in an ODBC-supporting database. Quality analysis covers jitter, delay variation, packet loss, and MOS-based call-quality prediction. Configurable alerts can flag problems for response. SIP and RTP packets can be saved as individual PCAP files for analysis or export. sipMON can record calls, decode speech, play it in its interface, or save audio as WAV. G.711 alaw and ulaw are listed, with commercial plugins for G.729a, G.723, iLBC, Speex, and GSM. CDR details may include duration, codec, caller information, SIP agent, last SIP response, RTP source addresses, MOS, delay and loss distributions, and download commands for WAV or PCAP files. The maker describes its C++ program as handling thousands of simultaneous calls. Ongoing-call monitoring is beta and requires the latest sipMON with TCP manager access enabled.

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.
