二 | 自去年11月29日起，中国电信Volte高清语音通话已全面开通商业试用。电信用户需要使用支持Volte的设备终端来启动服务。此外，他们需要重启手机或切换飞行模式，并在手机设置中启用Volte高清通话。手机信号栏显示HD或Volte，表示成功。用户可以尝试下载视频以测试呼叫是否成功。

三 | Volte，也称为Voice over LTE，也称为HD Voice。这就是手机中的“高清”图标的来源。它是一种基于4G网络的高质量语音和视频呼叫服务。Volte技术给4G用户带来最直接的感受是等待时间更短、质量更高、语音和视频通话效果更自然。Volte与2G和3G语音通话本质上不同。

四 | Volte是一种基于4G网络全IP的端到端语音方案。Volte使用高分辨率编码和解码技术，与2G和3G语音通话相比，它可以提高约40%的语音质量。Volte为用户带来较低的访问延迟（拨号后等待时间），比3G低50%，约2秒，而2G为6-7秒。此外，在2g和3g下，经常会出现辍学现象，但Volte的辍学率接近于零。
