SIP Sentinel

Introduction

Sentinel is SIP/RTP call quality analyzer which is independent on any used SIP/PBX proxy. Each call is stored to database along with quality metrics, SIP packets for later analyze (in pcap format) or full RTP or only RTP headers packets. Access to data is through WEB interface. Sentinel is also able to play sound directly from the WEB or download as a WAV.

Overview

Deploying sentinel sensor proactively (24h/day) helps to troubleshoot any sort of voice quality or SIP signaling problems. NOC employee do not need to sniff particular customer and use wireshark anymore for each reported case. Instead - if any problem arise - email report can be generated. Operator can look back to history data and check if some problem is systematic or adhoc.

SIP response overview shows SIP last SIP response. Clicking on response will filter all those CDR for detailed analyze.

Each call has two graphs for RTP stream showing jitter and loss distribution:
Quick CDR overview - operator can search in CDR based on any criteria - IP, DID numbers, callerid, sip agent, domains, call quality (MOS score, RTP jitter/loss, RTCP jitter/loss) SIP response and other criteria.
Each CDR can be unfolded to see detail of the call with RTP / RTCP metrics and SIP flow. SIP Message (like Wireshark)
Packet Details
Various sort of data can be plotted and saved as a pdf - for example show number of max/avg/min concurrent calls for whole system or for some SIP trunk or customer:
SIP response codes distribution (quickly shows any 5XX, 6XX anomalies)
Charts can be created from any value like this showing PDD and CANCELED calls correlation
Plot creator formular (each custom plot can be saved for future use)
Pie Charts for quick overall view of call successes & failures.
Active calls - Sentinel can show all current calls with filter possibilities.

===REPORTS====

Alerts - Sentinel is able to send email alert based on SIP or RTP criteria. For example - send alert if 5XX SIP responses are over 3% or if MOS score lower than 3.5 is for 2% of calls. Each alert are also saved in database for future reference.
Report generator is used to do instant reports or save report criteria and send (and save) daily report based on quality criteria.
Basic call summary - shows quick overview for IP addresses to see ASR and ACD
QoS summary - shows MOS jitter delay loss statistics for IP addresses
Advanced search system never fails you.
