One Pane of Glass – EOM/OCOM is a unique Service Assurance platform, showing the current state and all past states of all users, calls, registrations and SIP events. EOM/OCOM slices your telephony service [SS7, MeGaCo, SIP] in all possible dimensions, e.g. calls, users, devices, endpoints, SIP trunks and brings it all onto “one pane of glass” giving you perfect visibility of your service as experienced by all users.

Call Flow – Unique call merging algorithm stitches together all legs of the call, regardless of any manipulation of SIP or SDP by the network devices. The OCOM call merging algorithm has never failed to provide perfect call correlation.

Service Assurance – EOM/OCOM’s unique approach with stateful monitoring of every call and transaction, allows instant detection of common but previously obscure events such as dropped VoIP calls and one-way audio. These, and many more are all automatically detected. This is true Service Assurance and only available with EOM/OCOM.

Easy to Use – One display gives you perfect visibility, real time, on all your calls, allowing swift drill down by any criteria, using intuitive filters presented conveniently.

Use KPIs already configured such as the comprehensive IETF defined measurements for extended telephony performance such as Answer Seize Ratio [ASR] and Post Dial Delay [PDD].

Or build your own Key Performance Indicators. You can configure EOM/OCOM with a vast range of KPIs e.g. any SIP Response, METHOD, TCP sessions, long calls, short calls, errors, media events … you name it, all from a simple GUI wizard. Once you’ve built your KPI, you can configure thresholds for smart alerts.

Identify Poor Voice Quality – Identify intermittent poor voice quality with granular metrics over time.

Easily Find Bad Calls – Identify all calls with poor voice quality using a simple filter that is there, in plain sight, on the calls page.

Easy to follow flows – Perfect call merging correlates all legs of the call. User defined names are given to each device e.g. “Access 4” above. In addition, colored IP Tags and Prefix Tags label specific interfaces or traffic types within a device e.g. distinguishing the SIP signaling IP addresses from the media IP addresses within the same SBC or SIP trunk.

Global Monitoring: Scale your real-time Service Assurance across continents, optimizing use of bandwidth but ensuring all calls perfectly correlated.

OCOM Key Functions and Features

OCOM helps network operators improve their productivity and efficiency by providing a high-level overview of what is actually happening in the network in real time with drill-down capability for rapid troubleshooting. Some of the key features include:

  • End-to-end call correlation and analytics in real-time.
  • Segmentation of the network path for fast and accurate problem localization.
  • On-demand troubleshooting down to the individual employee, agent, or customer level.
  • Media quality analysis, including R-value scores and mean opinion scores (MOSs).
  • Unparalleled insight and analysis of signaling messages.
  • Real-time scoring and alerting to VoIP fraud issues.
  • Software embedded in Oracle E-SBCs and ECB eliminates the need to place additional monitoring equipment in the network.
  • Intuitive and simple graphical user interface (GUI).

OCOM is a passive service assurance suite that enables proactive monitoring, rapid troubleshooting, and an array of reporting options. Some of the key functions include.

  • Captures traffic from VoIP and UC networks.
  • Collects raw messages from probes and correlates these messages into end-to-end call message flows.
  • Calculates 200 out-of-the-box, custom key performance indicators (KPIs).
  • Renders gathered data to a web interface and makes it available to external applications via the REST API.
  • Enables fast root cause analysis with intuitive drill-down capabilities to a per-message view.

Proactive SIP Monitoring

OCOM analyzes the received traffic and triggers alerts when thresholds are exceeded. It detects and generates alerts for network abuse, fraud, spam over internet telephony, and denial of service attacks. OCOM can connect multiple applications and allows for integration with existing applications. It offers a web interface that is easy to use for non-technical staff and that includes multiple fault and trend views to help identify potential service quality degradations in a VoIP network. For example, voice quality status is reflected in the colors used by OCOM to display charts, which appear green or red based on the values of MOS, R-factor, packet loss, burst loss, and jitter.

Troubleshooting and Visibility

OCOM identifies each leg of a session in real time. This feature is essential for troubleshooting and for providing deep device visibility and accurate statistics. OCOM’s approach to SIP Monitoring is unique and it correlates all call legs, covering any vendor implementations. Its analysis contains ALL protocol information, including the following:

  • KPIs.
  • Call status.
  • Call duration.
  • Codecs used.
  • Call audio quality.

Integration and Reporting

OCOM offers a collection of  addon tools and services that simplify integration and interoperability with a range of network management system, business intelligence, and customer relationship management applications. A scripting API enables local access to all the data gathered by OCOM using Python for stateful detailed parsing, and a REST API enables external applications to access OCOM data. For example, an external application can gather custom data such as the list of users registered from a phone with special firmware, successful call rate, or number of users with more than two contacts. The resulting information can be used to build valuable statistics. OCOM also supports SNMP (Simple Network Management Protocol) for generating alerts to third-party applications. This integration flexibility makes OCOM future-proof for growing networks.

SIP Monitor Architecture


OCOM Probes collect and analyze data feeds from the network. Probes are deployed across the infrastructure to produce a network-wide view of performance and analyze trends. Probes serve two primary functions:

  1. Collect packet captures of signaling messages (SIP, ISDN User Part, and so on) and forward them to the OCOM Mediation Engine for correlation and analysis.
  2. Collect and analyze local RTP media streams and send the results to the Mediation Engine for correlation with relevant signaling information.

OCOM Probes are available in two form factors:

  • Software that can be loaded on COTS Linux servers. (OCOM Probe software is offered at no additional cost; servers must be procured independently).
  • Probes that are embedded into Oracle Enterprise Session Border Controllers and Oracle Enterprise Communications Broker.

This form factor enables network operators to optimize their IP communications networks while reducing network cost and complexity. The embedded probes leverage Oracle encryption technologies to gain visibility of network traffic.

SIP Monitor Mediation Engine

The OCOM Mediation Engine receives signaling and RTP stream metadata from the Probes and performs further processing, call correlation, and database functions. The Mediation Engine and Probes can be connected through secure channels for secure data transactions. The Mediation Engine performs massive processing and correlation of a wide range of messages to produce a network-wide view of all calls in real time. The OCOM Communications Operations Monitor renders the correlation, KPIs, and metrics, and an intuitive GUI simplifies analysis and troubleshooting operations.
