MTR

MTR traces from VoIPmonitor WEB server to selected IP using Linux mtr tool (10 seconds, 10 packets).

IP Lookup

IP lookup table substitutes IPs in places like CDR view, taking precedence over DNS. Enable via "database IP reverse lookup" in Settings > System Configuration.

Prefix Lookup

Prefix lookup table substitutes numbers in places like CDR view, taking precedence over IP lookup/DNS. Enable by setting ENABLE_SQL_CUSTOMER_PREFIX_LOOKUP to true in config/configuration.php.

Load PCAP

Upload PCAP files (libpcap format: tcpdump, tshark, Wireshark, voipmonitor). Processed by:

voipmonitor --config-file /etc/voipmonitor.conf -r upload.pcap

Change conf path in Settings > System Configuration > Upload sniffer conf path.

Batch Download CDR WAV

Download WAVs in batch via CSV upload.

Example CSV:

Details:

• Telephone: Caller or Called number.
• Lead Number: Identifies record in CSV log (exported with audio/PCAP).
• Start Time: Locates CDR; second pass uses +-5 minutes if not exact.

Concurrent Calls Stats

Shows max concurrent calls (connected) stats for last 14 days, averaged over 60-minute windows: Max average from minute-by-minute counts.

Applies to GUI licensing. Counts all CDR legs (e.g., 100 calls with 2 legs = 200). License needed for actual calls (e.g., 100).

If over license, sniffer continues but GUI warns/blocks in 14 days; contact support.
