What is VoIP (Voice over Internet Protocol)?
VoIP stands for Voice over Internet Protocol. It is a technology that allows voice communication and multimedia sessions over the internet instead of traditional phone lines. VoIP is widely used in call centers to reduce costs and increase flexibility.
How VoIP Works
VoIP converts analog voice signals into digital packets and transmits them over the internet. These packets are reassembled at the receiving end to produce high-quality voice communication.
Benefits of VoIP in Call Centers
– Lower communication costs compared to PSTN lines
– Scalable and flexible for remote or hybrid teams
– Easy integration with CRM, IVR, and ACD systems
– Advanced features like call routing, recording, and analytics
– Supports multichannel communication
Drawbacks of VoIP
– Dependent on stable internet connectivity
– Potential quality issues like jitter, latency, or dropped calls
– May require additional security measures to prevent SIP attacks
Types of VoIP Protocols
SIP (Session Initiation Protocol)
Commonly used for initiating, maintaining, and terminating VoIP calls.
RTP (Real-Time Transport Protocol)
Handles delivery of audio and video over IP networks.
H.323
Older protocol suite used for multimedia communication over IP networks.
Is VoIP Secure?
While VoIP is generally safe, it can be vulnerable to hacking or fraud if not properly secured. Best practices include encryption, firewall protection, and strong authentication protocols.
