Bicom Systems SIP Monitoring (sipMON) vs SolarWinds VoIP & Network Quality Manager

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. Pricing is on request.

SolarWinds VoIP & Network Quality Manager (VNQM) is a self-hosted tool for monitoring VoIP calls and WAN performance. It tracks jitter, latency, packet loss, round-trip time, and mean opinion score, with synthetic call tests and SIP trunk monitoring. Call detail and management records help locate affected calls, inspect paths, review quality metrics, and identify common error codes. Real-time alerts trigger when user-defined quality or network thresholds are exceeded. VNQM monitors Cisco IP SLA and Juniper RPM operations between source and target devices with current and historical QoS metrics. Supported call managers include Cisco Unified Communications Manager, Cisco CallManager Express, and Avaya Communication and Media Server. It runs on the SolarWinds Platform with web and Windows access. The listed plan including VNQM costs $8 per month; VNQM does not support over six million calls monthly.
