I bought TP Link XC220 - G3v model. I have configured internet (BSNL - India) and its working. But I couldn't configure Voip to use telephone. Please guide me. I couldn't upgrade firmware too.
Hi, is this modem provided by BSNL? Since it is a customized model for local internet service providers, both the internet and VOIP configuration need to be pre-configured with the help of service providers.
Thank you very much.
