Sample project for calling Microsoft Flow using 'custom connector'.

This code will set up a contact flow/IVR for real time authentication with Mobile BankID and can be deployed in minutes.

Turn telecom signalling captures into explained call-flow ladders — 5G core, 4G EPC, IMS

Insilode: the open-source code editor built on VS Code that shows how your code runs: a live call-flow canvas of every request, and Claude Code and Codex side by side.

Provides interface, design details of ngtcp2. Future, will provide easy to use ngtcp2 APIs pre-integrated with various events/ssl libs.

flux3D is an open-source, immersive 3D visualizer for Five9 IVR call flows. Walk through your IVR logic with a holographic avatar, animated data cables, real-time analytics, and interactive module inspection.

Visual dial-plan editor for FreePBX and read-only visualizer for VitalPBX — see every route, build forward.

A minimal Python application demonstrating best practices for customer service call flows using FastAPI and Vonage APIs. It uses a SQLite database to simulate a CRM used for call personalization and interaction logging.

IVR self-service call-flow engine: declarative JSON call flows (DTMF and speech menus, digit collection, caller identification, self-service actions, transfers), static flow validator, deterministic interpreter with event log, scripted call-flow tests, synthetic caller simulator, call-data analytics with z-test comparison of flow versions, 153 test

Python telecom simulator demonstrating how VoIP calls work in an IMS-style network. The project simulates SIP call initiation, Diameter-based authentication against a subscriber database (HSS), and RTP voice session setup. Includes logging and a simplified architecture explained using a restaurant analogy to visualize telecom call flows

Create SIPp XML scenarios online for free — no need to write raw XML! This free web tool lets you easily build SIP call flows and export valid XML files for use with SIPp, a popular SIP testing tool.

A reference guide to mobile core network architecture and signaling procedures, with call flows and citations to relevant 3GPP TS clauses.
