Kotha IP PBX is a feature-rich, enterprise-grade IP telephony platform built for businesses of all sizes. Manage your entire voice infrastructure — extensions, SIP trunks, IVR, call queues, recordings, and voice broadcasting — all from a single, powerful dashboard.
Kotha IP PBX combines professional telephony with modern software — self-hosted on your own server, fully under your control.
Full SIP & PJSIP extension management with caller ID, voicemail, per-extension call recording, and real-time registration monitoring. Supports registration, IP-based and gateway trunks with automatic failover, codec control (G.711, G.729, GSM, Opus) and bulk capacity management.
Multi-level auto-attendant menus with custom audio, multi-digit options (0–9, *, #), nested IVR, loop and timeout handling. Pattern-based outbound and DID-based inbound routing with office hours, holiday schedules, and per-route caller ID override.
Professional ACD with 7 strategies: ringall, leastrecent, fewestcalls, random, rrmemory, linear, wrandom. Agent pause/resume, hold announcements, position announcements. Smart callback queue — callers opt for a callback instead of waiting on hold.
Bulk voice calls to thousands of contacts from phone lists. Scheduled recurring campaigns with working-day restrictions, timezone support, CSV import, and retry logic. Real-time broadcast monitor with pause/resume/cancel and DNC integration.
Complete call logs with timestamps, direction, duration, disposition, and recording links. Agent performance reports with AHT, inbound vs outbound. Broadcast history with answer rates. Real-time dashboard — live CPU, memory, call metrics, and trunk balance history.
Full-screen dashboard showing active calls, queue status, agent availability, and system health — powered by WebSocket and Asterisk AMI. Queue monitor tracks waiting calls, agent utilisation, and API call source/domain per active call.
Do Not Call list with bulk CSV import, source tracking, and audit trail — auto-checked before every outbound call for legal compliance. Configurable spam filters with custom block audio, duration-based temp blocks, and schedule-based activation.
Full REST API with API key auth and IP whitelist. Trigger voice blasts and quick calls, check status, list audio files — GET and POST. WebSocket API streams real-time call events. Ideal for CRM, RADIUS billing, click-to-call, and alert systems.
Role-based access (Admin, Operator, Viewer) with fine-grained per-feature permissions. UFW firewall management, Fail2ban brute-force protection, Let's Encrypt SSL automation, one-click system backup and restore, and centralized audio library.
Built on battle-tested open-source foundations. Self-hosted on Debian — no cloud dependency, no vendor lock-in.
Trusted by call centers, enterprises, ISPs, and telecom providers across Bangladesh.
