I used Linphone SDK to develop an Android application, everything is good but when a caller call without internet connection it entered well but after 1 min it didn't enter, it shows network busy. For example:
- User A have internet and user B don't have internet it can make call to each other successfully.
- After one minute, when user B make call to user A, network busy shows to user B, but user A make call to user B successfully any time.
- User A is registered with server and user c also registered with server have the same problem.
is there any way to fix it?
