Version 2.6.3

- We updated for :

1) To pause sound as default when you are encountered to the advertisement of streaming after finishing your call for your better convenience.

2) Recently, we seriously recognized that we are in the state of being provided low voice quality to our customers. So as for now, we've decided to improve the voice quality of the call for better service to our customers. It will take a few weeks to improve this from now on.
