Indian ISPs actively throttle VoIP services during peak hours — your Zoom meetings freeze, Teams calls drop, and WhatsApp video stutters. This isn't your internet speed; it's your ISP deliberately slowing VoIP traffic to manage bandwidth. A VPN encrypts your traffic so your ISP cannot identify and throttle VoIP packets. Additionally, business conversations on video calls contain sensitive information that should be encrypted end-to-end from your device through the network.
