A VoLTE GSM Gateway is an advanced communication device that allows voice calls to be transmitted over 4G LTE networks using Voice over LTE (VoLTE) technology. Unlike traditional GSM gateways that operate on 2G or 3G networks, a VoLTE GSM gateway offers high-definition voice quality, faster call setup, and better network efficiency by leveraging the IP-based infrastructure of LTE. https://www.gsmgateway.in/volte-gsm-gateway.html
