What We Deliver

End-to-End Enterprise Telephony Services

From custom on-premise Asterisk PBX engineering to bank-grade automated data pipelines and predictive algorithm tuning.

On-Premise & Cloud CTI Setup

Custom turnkey deployment on bare-metal Rocky Linux, CentOS, or AWS/GCP. We configure high-availability Asterisk PBX clusters, SIP trunks (Dinstar, Synway, Tata, Jio), and PRI gateways.

  • Bare-metal / Private Cloud
  • Multi-carrier Failover & LCR

Predictive Algorithm Tuning

Stop burning leads with crude auto-dialers. We calibrate Java CTI daemon pacing engines to dynamically balance agent idle times, telco drop rates, and line delays for 3.5x higher talk times.

  • Real-time Ratio Optimization
  • Zero Dropped Call Compliance

Custom CRM & Screen Pop

Sub-300ms screen pops tailored to your workflow. We build custom agent UI forms with loan history, disposition trees (PTP, RTP, NC), OTP verification, and dynamic field mappings.

  • WebSocket & DWR Push
  • API Integrations (Salesforce/Zoho)

Voice Blaster & Bulk IVR

High-throughput automated broadcasting engine handling 50,000+ calls/hr for EMI payment reminders, collections notifications, dynamic customer OTPs, and instant press-1 transfer to agent floor.

  • 120-1000+ Concurrent Channels
  • Multi-lingual Dynamic TTS

Secure SFTP & Data Ingestion

Built for BFSI data compliance. Automated SFTP ingestion pipelines with PGP/GPG decryption, real-time CSV sanitization, duplicate phone filtration, and lead lot allocation across agent roles.

  • PGP / GPG Auto Decryption
  • Auto-Repair Bad Characters

24/7 AMC & Telephony Support

Continuous monitoring of SIP channels, Asterisk core, MariaDB replication, and call quality. Our senior telecom engineers provide sub-15 minute SLA responses to keep your floor buzzing.

  • Live Trunk Health Audits
  • L1/L2/L3 Dedicated Engineers
About DialVox

Engineered by Telephony Purists,
Trusted by India's Top Call Centers.

DialVox was founded on a simple realization: modern contact centers were trapped between overly expensive cloud SaaS tools with high per-minute charges, and clunky, unreliable legacy dialers that break under heavy load.

We architected DialVox from the bare-metal up—fusing the raw power of Asterisk PJSIP with a custom multi-threaded Java CTI daemon and real-time WebSockets. The result? A battle-hardened dialing platform that processes over 100 Million outbound minutes every month with zero dropped audio packets.

Bank-Grade SFTP & GPG Security

Automated SFTP pipeline with GPG encryption/decryption, auto-sanitization of malformed CSVs, and duplicate number filtering built specifically for BFSI compliance.
