If there are no signals on your smartphone then there is no need to worry. If you do not have a mobile network, you will now be able to call your mobile or landline number using your home, office or public Wi-Fi network. All this will be possible with internet telephony. Telecom regulator TRAI has given its approval for internet telephony. 

Old Telecom Companies have protested against it. This will be particularly beneficial for making voice calls in those situations when there are no signals in the mobile or the traditional network is very weak. TRAI has said in its recommendation on the Internet Telephony Regulatory Framework that according to the existing licensing framework, internet telephony service can be made freely available. 

TRAI has described Internet voice calling as a convenient and affordable option. TRAI says that this step will increase the call rate. TRAI has expressed dissatisfaction over the opposition to telecom companies. TRAI says that there will be more options for calling users. 

Old Telecom companies believe that this step will have a bad effect on Voice Revenue. Companies say that if internet telephony is made available on the public network, it will cause huge losses to those operators who provide voice services. That's because it will shift the voice traffic to the public internet. It also said that due to the increase in the number of smartphones and tablets, SMS and Voice Traffic has shifted to app-based services, which has already affected their revenues.
