A 10-Second Technical Buffer Is Applied to Inbound Calls

Callers.io has a 10-second buffer that filters out audio and connectivity issues before a call is fully connected.

Understanding the 10-Second Buffer

When an incoming call begins, there's a brief 10-second pause. This allows the system to prepare before the call proceeds. The benefits of this buffer include:

• Eliminating dead air
• Reducing charges for lost calls due to quick disconnections
• Minimizing audio issues
• Enhancing overall call quality

The goal is to only charge agents for actual conversations, as technical problems shouldn't factor into the billing.

The Importance of the Buffer

Inbound calls can experience:

• Short delays in carrier routing
• Issues with consumer audio setups
• Connectivity problems

This slight delay helps prevent early glitches from being logged as complete calls.

Does It Ensure Perfect Calls?

Despite this buffer, some variations in voice signals may still occur. Factors affecting call clarity include:

• The device connecting to the network
• Carrier routing
• Geographic location
• Stability of the agent's internet
