VNYour agents shouldn't need three apps to do one job.
Most call centres run their dialer in one tab, their SMS tool in another, and chase live chat leads through a separate platform entirely. Agents toggle. Data gets lost. Managers lose visibility. Klozer.io puts calls, 2-Way SMS, and live chat on a single screen — with every interaction automatically logged to your CRM. One login. One dashboard. One bill.
Other dialers
Calls only. SMS is an add-on. Live chat is someone else's problem. Your agents live between tabs.
Klozer.io
Calls, 2-Way SMS, and Live Chat on one screen. Everything tracked. Everything CRM-synced. One agent handles all three.
Cobbled-together stack
Three vendors. Three contracts. Three support queues. Three invoices. Three points of failure.
Call any country. Look like a local. Get answered.

Frequently Asked Questions
What makes Klozer.io different from other call centre dialers?
What is the difference between Predictive, Power, and Preview dialers?
Think of them as three speeds for your sales floor:
- Predictive: The “Auto-Pilot.” It dials multiple lines and only connects your agent when a real human answers.
- Power: The “High-Speed” mode. It calls your list one by one automatically so your agents never have to stop.
- Preview: The “Research” mode. Your agent sees the customer’s history before the call starts, perfect for high-ticket sales.
How does automated Local Caller ID (CLI) rotation prevent "Spam Likely" flags?
Local CLI rotation increases pick-up rates by displaying familiar, localized area codes to prospects. Klozer’s per second auto-rotation technology prevents number “burn” by frequently switching IDs before they are flagged by carrier algorithms. This proactive management can increase connection rates by up to 40% while maintaining a “clean” caller ID reputation across all major telecom networks.
How does real-time Local Caller ID (CLI) Reputation Management work?
Klozer’s inbuilt CLI Reputation tool utilizes real-time analytics to monitor the “Health” of your caller IDs across major carrier networks. The system categorizes each CLI as either Healthy or Risky, providing an instant visual indicator of its reputation. Crucially, the tool displays the real-time Human Answer Percentage for every Caller ID (CLI). This allows call center team leaders to identify precisely when a CLI is being flagged or ignored, enabling them to make instant, data-driven decisions on rotating CLI batches. By removing “Risky” numbers before they waste agent time.
What is a Call Connection Score, and how does it optimize lead data ROI?
A Call Connection Score is a proprietary performance metric used to grade lead lists based on actual live answer rates and sales outcomes. By analyzing this data in real-time, call center managers can identify underperforming datasets (data bleeding) and instantly shift budget and agent resources toward high-ROI geographic areas or lead sources.
How does Call Conversation Scoring improve sales agent coaching?
Call Conversation Scoring utilizes conversation duration, rapport-building, and adherence to sales scripts. By identifying real-time report call centre managers can identify which agents are struggling and requires training or Top performing agents who are closing more sales across both remote and in-office teams, effectively closing the coaching gap through automated feedback.
Does Klozer integrate with HubSpot, Salesforce, Zoho, and Pipedrive?

Klozer provides integrations with all major CRM platforms including HubSpot, Salesforce, Zoho, and Pipedrive, plus 50+ additional third-party business applications and CRMs. Every call log, call recordings and call comments, and lead status update syncs automatically and instantly to your CRM eliminating manual data entry entirely. Klozer customers report saving an average of 12 hours per agent per week in administrative tasks, time that is redirected directly into selling. Integration setup is managed by Klozer’s technical team.
How fast can a cloud call center dialer be set up for remote agents?
With Klozer, a fully operational remote call centre including agents, supervisors, and reporting dashboards can be live in under 24 hours. Because Klozer is a 100% cloud-based solution, agents need nothing more than a standard web browser and a stable internet connection. There is no hardware to install, no VPN to configure, and no software to download. This “Agents Anywhere” architecture is designed specifically managing distributed teams across multiple cities, onshore or offshore BPO operations, and home-based agents across different time zones. Teams that migrated from on-premise dialler systems to Klozer report reducing their IT infrastructure costs by 30–40% in the first year alone.
What is the difference between a shared dialler and a dedicated dialler, and which is better for a BPO?
A shared dialler server splits resources across multiple businesses simultaneously meaning your call quality, uptime, and data maybe compromised with other companies on the same infrastructure. A dedicated dialler server gives your call centre exclusive use of all resources, guaranteeing consistent performance even during peak dialling hours and securing your dialing data and call recordings. Klozer specialises in dedicated server setups for BPOs and call centres with 5 to 500 agents. Each dedicated server comes with personalised onboarding, custom configuration for your campaign type, and 24/6 live technical chat support from Klozer’s award winning customer experience team. BPOs on dedicated Klozer servers report 99% uptime.
How does Answering Machine Detection (AMD) differentiate between a live human and a voicemail?
Klozer’s AI AMD uses signal processing to detect these patterns with 95%+ accuracy, ensuring agents are only connected to live human prospects and never waste time on voicemails.

Key features that drive its high ranking include Call conversation score, real-time CLI Reputation Management, and a dialing rate 3X faster than manual systems, which collectively increase connection rates by up to 40%.
Is Klozer a better option than VICIdial for a call centre without an in-house IT team?
VICIdial is a open-source dialler but it requires dedicated expertise to install, configure, and maintain. For call centres managing a VICIdial server means either hiring a system administrator or relying on costly third-party developers for every update, bug fix, or campaign configuration change. Klozer is the fully managed alternative that delivers the same enterprise-grade dialling power in a 100% cloud-hosted environment with zero technical overhead. Setup takes under 24 hours, requires no server knowledge, and includes Klozer’s 24/6 technical support team as part of every plan.

Klozer delivers VICIdial-level power without the VICIdial-level complexity.
What call centre software features are essential for managing remote or offshore agents?
Managing remote or offshore agents introduces challenges such as lack of real-time visibility, inconsistent coaching, data security risks, and time zone complexity. The essential features required to manage distributed teams effectively are: a web-based dialler that works without VPNs or hardware (ensuring agents in the Philippines, India, or any region can connect instantly); a real-time Remote Management Wallboard showing every agent’s real-time status, call outcomes, and KPIs from a single dashboard; Monitoring and Whisper Coaching that allows supervisors to speak directly into an agent’s ear during a live call without the prospect hearing; Call Conversation Scoring that automates performance feedback without requiring supervisors to manually review all call recordings; and automatic time zone routing to ensure prospects are only called during legal hours regardless of where the agent is located. Klozer’s platform includes all five features as standard making it the leading solution for managing remote and offshore/onshore call centre operations.
