Enterprise Telephony / IP-PBX
Enterprise IP telephony and voice infrastructure supporting business communications, extension management, SIP connectivity, call routing, mobility and integration with broader ICT environments. We engineer high-availability voice platforms with secure signaling, clear acoustic audio, and enterprise trunk redundancy.
Enterprise Voice & IP-PBX Infrastructure Architecture
HORNET INFOTECH designs, deploys, and maintains enterprise IP telephony solutions. We integrate reliable IP-PBX switching servers, enterprise IP handsets, softphones, SIP trunk gateways, intelligent call routing, and complete unified communications for commercial and institutional organizations.
Scalable extension management, multi-level IVR and automated attendants, dynamic call routing policies, and departmental hunt groups or call queues configured to enterprise workflows.
High-capacity SIP trunk integration, Session Border Controller (SBC) security, PSTN / E1 / PRI gateway integration, Direct Inward Dialing (DID) number management, and designed failover routing.
Executive touchscreen IP desk phones, standard gigabit desktop handsets, PC and mobile softphone clients, wireless conference units, and specialized reception/operator attendant consoles.
Voicemail-to-email integration, presence and mobile twinning where supported, detailed Call Detail Record (CDR) analytics, voice quality monitoring, professional commissioning, and scheduled AMC support.
7-Stage Enterprise Telephony Ecosystem
From user endpoints and prioritized PoE network infrastructure to redundant call controllers, external SIP trunks, and voice quality analytics, every stage is optimized for voice availability.
Endpoints
Gigabit IP desk phones, wireless DECT/Wi-Fi handsets, executive touchscreen phones, and PC/mobile softphone clients.
Access Network
Structured Cat 6A horizontal cabling, workstation RJ45 dual-gang faceplates, and automatic voice VLAN classification.
Network Access & PoE/QoS Infrastructure
Managed IEEE 802.3af/at PoE+ switches, Layer-2 802.1p Class of Service tagging, and uninterrupted power supply feeds.
IP-PBX Call Server
On-premise appliance or virtualized call server, extension management, multi-level IVR, and dual-server failover.
SIP Trunk / PSTN
High-reliability SIP trunk connectivity, Session Border Controllers (SBC), and E1/PRI digital or FXO analog voice gateways.
Unified Comms
Integrated voicemail-to-email, user presence, mobile softphone mobility, CRM click-to-dial, and conference bridges.
Monitoring & AMC
Call Detail Record (CDR) analytics, Mean Opinion Score (MOS) voice quality tracking, trunk failover alerts, and scheduled AMC.
Deployment Environments & Operational Profiles
Enterprise telephony requires tailored engineering based on extension counts, concurrent call densities, call queuing complexity, external trunk failover paths, and mobility requirements.
Corporate Offices
Multi-extension corporate headquarters with automated IVR attendants, departmental hunt groups, centralized directory integration, and hybrid worker softphone twinning.
IT / ITES & Support Centres
High-density customer support teams requiring automatic call distribution (ACD), supervisor whisper/barge-in monitoring, call recording servers, and CRM dialer integration.
Healthcare Campuses
Hospitals and medical facilities requiring rapid emergency code dialing, nurse-station speed dials, wireless DECT handsets for roving medical staff, and bedside analog gateways.
Educational Institutions
University and school campuses interconnecting faculty offices, security gatehouses, classroom intercoms, administrative wings, and campus emergency hotlines.
Hotels & Hospitality
Hotels and resorts with guestroom IP/analog phones, property management system (PMS) integration, automated wake-up call scheduling, and front-desk billing interfaces.
Government / Institutional
Government secretariats and institutional complexes demanding high-availability on-premise call controllers, encrypted SRTP/TLS voice packets, and survivable remote branch units.
Detailed Technical Specifications & Design Review
Extension schedules, IP-phone hardware schedules, IP-PBX call controller capacity, SIP connectivity, PSTN gateway requirements, PoE/network requirements, call-flow diagrams, and vendor-neutral BOQ formulation are prepared by our engineering team based on project specifications.
Documented Project Deployments
Verified institutional infrastructure delivered, commissioned, and handed over by HORNET INFOTECH.
