Hello Jitender_Kumar_Misra, thanks for your question
Our EC200T-CN module already supported VoLTE function, but this funtion achieved base on R05 baseline. Your module do not support VoLTE if your module was R02 baseline or R03 baseline(you can query the baseline of module by ATI command). R02&R03 baseline can not upgrade to R05 baseline directly,.If you want use volte funtion, you can request new sample from quectel or you can send your module to us, we will upgrade and calibrate your module, thank you.
