Application Notes

Developing Call Monitoring Applications Using Dialogic® SS7 Signaling and Media Products
This application note provides information about developing a call monitoring application using the Dialogic® SS7 signaling and media products. Dialogic developed a sample application that provides both a starting point and a reference for those who choose to develop an SS7-based application that monitors SS7 links and records calls on the links. Call recording can be triggered based on information related to the call. Calls may be recorded to multiple files or streamed through the data network for real-time monitoring.
USSD Services for Interactive Mobile Users
The application note describes the implementation of an interactive Unstructured Supplementary Service Data (USSD) service for GSM mobile users.  Sample code is included within the document.
Configuring an SS7 Demo System Using Dialogic® DSI Components with Dialogic® HMP Software Release 3.1LIN

This application note presents an SS7 demo system using Dialogic® DSI Components (SS7) with Dialogic® HMP Software Release 3.1LIN to demonstrate to users familiar with SS7 concepts that the SS7 configuration process can occur very quickly.
Using Dialogic® Distributed Signaling Interface Components for IS-41 Short Message Service
This application note provides a demonstration and information about developing an IS-41 SMSC application that combines the functions of SMSC and SME using Dialogic® DSI Components.
Enabling Dual-Chassis Fault Tolerance with the Dialogic® DSI SIGTRAN Stack
This application note describes how the DSI SIGTRAN Stack can be used to create a dual-resilient SIGTRAN M3UA-based platform that offers high availability and a high degree of fault tolerance.
Color Ring Back Tone — Building Feature-Rich Wireless Applications with Dialogic® Signaling Solutions
This application note describes the implementation of a Color Ring Back Tone (CRBT) wireless service. Focusing on the technologies and signaling involved, this document demonstrates how service providers can integrate CRBT into an existing Signaling System 7 (SS7) wireless application using Dialogic® Signaling Distributed Architecture (SigDiA) enabled building blocks.
Creating SS7 Circuit-Switched Applications using Dialogic® Global Call API
This application note describes the installation and configuration of circuit-switched telephony systems that combine Dialogic® Signaling Boards and Dialogic® DM3 Media Boards on platforms based on Linux and Windows® operating systems.
Adding Location-Based Services to Existing Architectures
This application note provides an overall view of Location-Based Services (LBS), describes the signaling and technology involved, and discusses how Dialogic® signaling components can be used in implementing such services.

Case Studies

JSC Ingenium Allows CELL C to Offer SIP-Based Services via SS7 to Its Subscribers
With its CAMEL IWF (InterWorking Function) Gateway, JSC Ingenium is allowing CELL C, the third largest mobile operator in South Africa, to integrate exciting next-generation SIP-based value-added mobile services into its conventional SS7 network. JSC Ingenium uses Dialogic® Distributed Signaling Interface (DSI) Components for signaling, switching, and transcoding in its CAMEL IWF Gateway and other solutions because DSI Components help to make these solutions easy to deploy, interoperable with TDM or IP, and very scalable.
Etisalat Sri Lanka Deploys Globitel's Roaming Solutions for Its More Than 3.5 Million Customers

Etisalat Sri Lanka understands both the challenges and the importance of providing unique and sustainable roaming services to attract customers, whether inbound or outbound. Because quality and user satisfaction are top criteria, Etisalat Sri Lanka chose three of Globitel's Roaming Solutions (Feel@Home, RoamSalute, and Intelligent Traffic Steering) because they aim to provide high levels of reliability and interactivity. These services also encourage roamer loyalty with superior quality and a user-specific interface that easily promotes SMS and data usage while allowing insight into roamer behaviors and service usability tracking.
Pharos Avantgard SMS System V Handles More Than 50 Million Messages Per Day for MTN South Africa's 20 Million Mobile Subscribers

mCarbon Delivers Versatile Call Management Service for Major Carriers in India
mCarbon has deployed a sophisticated call management service for major carriers in India using its GreenRoom framework and Dialogic® products for call control, signaling, and media.
SNT Multiconnect Moves to Open Infrastructure without Sacrificing Carrier-Grade Availability
SNT Multiconnect chose ConverCom's Carrier Service Factory, which combines the benefits of conventional SS7 technology with those of open systems by using Dialogic® components and the carrier-grade integration of Envox multi-channel communications functionality in its move to a more flexible network.
Call Notify SMS Service Helps GloBul Build Customer Satisfaction
GloBul, the second-largest wireless operator in Bulgaria, has added a new service to help its customers handle missed calls. The new service, known as Call Notify, was built on the JN Missed Call Notification (MCN) system from Bulgarian telecom solution supplier Applicata, and was based on a fully redundant SS7 configuration from Dialogic.
