Comparing Analog and IP Call Centers

Reading time: 5 minutes

Are you looking to invest in a professional call center system for your business but still unsure which type to choose? OMICall will compare the Analog and IP call center systems — currently the two most popular options — to help you make the most suitable choice!

What Is an Analog Call Center?

An Analog call center, also known as a traditional call center, works by converting voice signals into electronic waves of varying frequencies and amplitudes. Based on relatively long-standing analog voice technology, calls are transmitted through postal telephone lines. To use the system, the provider runs wiring from the post office to the location where the business’s call center is installed.

A basic traditional call center system consists of:

• Telephone switchboard
• Trunk lines
• Extension phones
• Cable box

9 Limitations of Analog Call Centers

Due to its fairly outdated technology, there are several limitations to consider before installing an Analog call center:

• Only connects internally within a single office (multiple offices require separate call center setups and cannot be linked together)
• Only a few basic features available: internal calls, outbound calls, and inbound calls
• Fixed configuration — expansion or upgrades are very difficult
• No API available for integration with other software
• High call charges
• High maintenance and repair costs

With an Analog telephone system, you will incur staff costs for system administration, labor costs when making feature changes, as well as maintenance and operational expenses. Although an Analog call center operates independently of supporting factors such as electricity and internet, its basic call functionality is simply not enough for today’s businesses, which require much more. For this reason, over time, Analog has gradually become outdated and is being replaced by a smarter alternative — the IP Call Center.

What Is an IP Call Center?

An IP call center operates based on cloud computing technology — a modern technology platform widely used around the world. Vietnam has been and continues to integrate and apply this technology more extensively in real-world business operations.

Benefits of IP Call Centers for Businesses

With the following advantages, an IP call center can fully replace an Analog call center to better support business operations:

• Utilizes the company’s existing internal Internet infrastructure — no complex installation required
• No geographical limitations: a single call center can be used across multiple branches in different locations
• Customer information management: call recording, data storage, and more
• Easy to upgrade and expand
• Integrates with CRM, ERP, and other systems
• Reduces call costs by up to 50%, with free internal calls
• Easy to use on smartphones, tablets, PCs, and more

Comparing Analog and IP Call Centers

Comparing Analog and IP Call Centers

1. Type of System

• Analog: Hardware-based, using a cumbersome and complex physical channel switching principle (TDM).
• IP: Software-based, enabling calls and multiple features over an Internet Protocol (IP) network infrastructure.

2. Cross-Department/Branch Operability

• Analog: Requires a separate call center system for each branch, making internal communication between extensions across branches impossible.
• IP: Only one call center at the headquarters is needed — no separate hardware required at each branch.

3. Integration Capability

• Analog: Integrating with other software requires additional compatible hardware investments.
• IP: Easily integrates multiple sales channels and management tools on a single platform.

4. Extended Support Features

• Analog: Only supports basic inbound and outbound calls.
• IP: Supports a wide range of features including auto call, auto-answer, call recording, video calls, ticket logging, and more.

5. Extension Scalability

• Analog: Limited number of extensions (line capacity).
• IP: Unlimited extension expansion (up to 10,000 users).

6. Investment Cost

• Analog: Expensive, with high costs from installation, phones, cabling, maintenance, and repairs.
• IP: Low cost, saving up to 50% — no wiring fees, no trunk cables, and no distance limitations.

7. Relocation

• Analog: Moving the system to a new location requires new cabling and full reconfiguration from scratch.
• IP: No additional costs — simply connect to the network and it’s ready to use.

8. Troubleshooting

• Analog: Requires hiring technicians for periodic line inspections, as it is difficult to identify where cable faults occur. Maintenance costs are extremely high and time-consuming.
• IP: Faults are easily identified through on-screen notifications, allowing quick and timely adjustments.

9. Management Capability

• Analog: Difficult to manage — any configuration changes require physically visiting the call center location.
• IP: Easy to manage — settings can be configured remotely via the web.

Conclusion

Regardless of the industry you operate in, customer care is an indispensable part of any business — and installing a call center system is something you simply cannot overlook. The market offers many different systems to choose from, but they all share the same core purposes:

• Increasing voice-based customer interaction
• Strengthening brand recognition through a dedicated call center number
• Providing convenience for both customers and staff in receiving and conveying information
