PAiCore Service Delivery Platform (SDP) is an open-source, carrier-grade platform designed to enable telecom operators and service providers to rapidly design, deploy, and manage real-time communication services.

The SDP provides a unified environment that allows MNOs, MVNOs, Value-Added Service providers, and enterprises to quickly deploy real-time communication applications with capabilities such as:

• Geolocation services via a dedicated Geolocation API
• Voice services including IVR, PBX, and WebRTC
• USSD menu applications for multiple service use cases

PAiCore SDP supports native telecom protocols, ensuring reliable integration between MNO/MVNO back-end systems and flexible API-driven communication for VAS providers and enterprises.

The platform also includes a No-Code Service Creation Environment (SCE), enabling rapid service design without deep protocol expertise.

Key features include:

• Geolocation API powered by PAiCore’s GMLC
• Integrated WebRTC capabilities
• Service Creation Environment (SCE) for quick creation of call, messaging, and geolocation flows
• Support for integration with external charging and policy systems

The platform follows a modular architecture where service logic, configuration, and runtime components are clearly separated.

High-level components include:

• Core SDP services – service orchestration and mediation logic
• Restcomm integration layer – interaction with Restcomm components
• Configuration and build tooling – scripts and descriptors under release/
• Extension modules – feature-specific logic under liveCallModification/

Detailed diagrams are available in the architecture_diagrams/ directory.

Note:
The release/ directory contains build and configuration scripts only.
It does not include compiled artifacts or binary distributions.

Before installing PAiCore SDP, ensure the following requirements are met:

• Java 11 (OpenJDK recommended)
• Maven 3.x
• Linux-based environment (recommended)
• PAiCore SIP Servlets (SDP core engine)
• Access to an Artifactory / Maven repository

Important:
PAiCore SDP depends on SIP Servlets as its core signaling and execution engine.
SIP Servlets must be built and published to a Maven-compatible repository (Artifactory) before building SDP.

git clone https://github.com/paicbd/sip-servlets.git
cd sip-servlets
mvn clean install

This step compiles all SIP Servlets modules and prepares the artifacts for publication.

mvn deploy

Ensure you have a valid settings.xml configured with your Artifactory credentials and repository URL.

git clone https://github.com/paicbd/SDP.git
cd SDP

mvn clean install -DskipTests
./build.sh

During this step, SDP will resolve SIP Servlets dependencies from Artifactory.
