The decision between a cloud-hosted dialer and an on-premise dialer is one of the most significant technology choices a call center makes. Both have genuine advantages. The right answer depends on your specific operation — and in 2025, the landscape has shifted considerably in favour of cloud for most use cases.
What Is a Cloud Hosted Dialer?
A cloud dialer is hosted and managed on servers owned and operated by your vendor. You access it via the internet through a web browser or a lightweight client application. You pay a monthly subscription fee, and the vendor handles all hardware maintenance, software updates, security patches, and infrastructure redundancy.
What Is an On-Premise Dialer?
An on-premise dialer is installed and runs on servers physically located in your office or data center. You own or lease the hardware, and your IT team is responsible for maintenance, backups, updates, and troubleshooting. Most on-premise deployments are built on open-source platforms like Asterisk or FreeSWITCH.
Detailed Comparison
Upfront Cost
Cloud: Near-zero upfront investment. Initial setup costs typically Rs 10,000 to Rs 50,000 for configuration and training.
On-Premise: Significant upfront investment. Servers, PRI gateways, telephony boards, and installation typically cost Rs 2,00,000 to Rs 15,00,000 depending on scale.
Scalability
Cloud: Scale from 5 to 500 seats in hours. No procurement, no hardware installation, no lead times. Perfect for seasonal businesses or rapidly growing operations.
On-Premise: Adding capacity requires hardware procurement and installation. Lead time of days to weeks.
Reliability and Uptime
Cloud: Enterprise-grade cloud providers offer 99.9% plus uptime SLAs with automatic failover and geographic redundancy.
On-Premise: Reliability depends entirely on your infrastructure quality and IT team capability.
Customisation
Cloud: Limited to features offered by your vendor. Good vendors like Avyukta offer extensive configuration options.
On-Premise: Maximum customisation. Full access to the underlying system means you can build bespoke features and integrations.
Which Should You Choose?
Choose Cloud if: You are a new or growing BPO, have fewer than 75 seats, your seat count varies month-to-month, you lack dedicated IT infrastructure, or you want to be operational within days rather than weeks.
Choose On-Premise if: You have a large stable operation of 100 plus seats, need maximum customisation, have compliance requirements mandating on-premise data storage, and are planning a 5+ year deployment horizon.
The Hybrid Approach
An increasingly popular option: run your primary operation on-premise for maximum control and cost efficiency, with cloud-based overflow capacity that activates automatically when your on-premise system reaches capacity. Avyukta Intellicall supports hybrid deployments for clients who need this flexibility.
