  • the present invention relates to a system and a method of video communication; more particularly to a system and a method of video communication between the participants wherein at least one of the participants has a cellular device.
  • the factors that preclude video calling include: i. A certain section of the cellular subscribers might not have the required generation of a SIM card that enables native video calling; ii. A certain section of the cellular subscribers might not have handsets that are compatible with the generation of SIM cards that enable native video calling; iii. Inter-carrier video calling between subscribers of different telecom carriers might not be possible as one of the carriers may not have a required infrastructure that supports video calling; and iv. Inter-carrier video calling between subscribers of different telecom carriers might not be possible as these carriers may fail to arrive at an agreement from a billing, regulatory, monitoring, or maintenance perspective.
  • the quality and “fate” of video call - which includes both an audio and video stream is dependent on the quality of the data connection at the caller or callee end (when video calls are made between subscribers of a purpose-built calling application).
