I've set up FriendCaller (http://www.friendcaller.com/) on my Nokia C3-01 V 05.60.
Connected the device to WiFi and tried a call between a PC and the C3.
The call works perfectly, however I have no sound (voice). Between 2 PCs (also connected to the same WiFi) there is no problem. (I have sound)
Are there any extra settings needed on C3 for the voice to work.
PS: The same no voice (sound) issue happens between 2 mobile devices connected to WiFi.
Thank you very much for your help.
