About Project

NextCall is an advanced mobile cloud PBX control and communication suite that turns smartphones into fully manageable enterprise phone terminals. Beyond traditional softphone capabilities, NextCall empowers administrators and mobile workers to reconfigure complex cloud PBX routing logic on the fly. Users can customize interactive voice response (IVR) flows, toggle Do Not Disturb modes, adjust Hunt Group queues, define Follow-Me rules, and dynamically select outgoing caller identities directly from a native mobile application. NextCall integrates proprietary dual-mode callback technology engineered to guarantee communication continuity even when data connectivity is severely degraded. When VoIP signal quality drops below acceptable thresholds, the application automatically initiates an intelligent cellular PSTN callback bridge, ensuring that business conversations remain uninterrupted, secure, and impeccably clear across all environments.

The Challenge

Field agents suffered from dropped VoIP calls on fluctuating cellular connections and had no way to reconfigure PBX call routing without desktop administrator access.

VoIP audio severe distortion and dropped calls on fluctuating cellular data networks

No mobile access to administrative PBX settings, queue rules, or call routing logic

Rigid caller ID handling preventing employees from toggling outbound business identities

Inability to track real-time network latency or codec health during critical client calls

Lack of automated failover routing when mobile data bandwidth falls below VoIP threshold

Inconsistent incoming call routing schedules when team members transition across timezones

Absence of one-touch emergency call redirection protocols for unexpected office closures

Complex Hunt Group reassignments requiring desktop browser access for field supervisors

The Solution

Engineered smart callback failover routing to maintain call quality on weak connections, coupled with real-time mobile PBX configuration controls.

Proprietary callback routing technology bridging calls via PSTN when data drops

Complete mobile PBX administration for Queues, Follow Me rules, and Do Not Disturb

Dynamic outbound caller ID selection directly from the mobile dialer screen

Live audio metrics panel showing real-time jitter, Opus codec status, and packet health

Automated network health checks and instantaneous fallback protocol switching

Location-aware business hours scheduling adjusting ring sequences automatically

Instant emergency failover toggle rerouting all tenant lines to contingency branches

Mobile-optimized drag-and-drop Hunt Group agent reallocation interface

The Results

Deployed as the primary mobile client for Cloud PBX business customers. Available on both App Store and Google Play. Real-time call monitoring with live codec, jitter, latency, and packet loss data. Full PBX settings management from mobile — Do Not Disturb, Follow Me, Queues, Outbound Number. Callback technology ensures call continuity on weak or unstable connections.
