What is the function of router in voip?

In VoIP (Voice over internet Protocol), a router facilitates the transmission of voice data over the internet by directing packets of audio information between users. It manages network traffic to ensure quality of service (QoS), prioritizing voice packets to minimize latency and jitter. Additionally, routers can provide security features like firewalls and encryption to protect VoIP communications from potential threats. Overall, the router plays a crucial role in maintaining the clarity and reliability of voice calls over IP networks.
