As the title suggest, VOIP Stunt offer free unlimited call to all fixed line in Malaysia as long as you purchase a credit of 10 Euro that will expire in 120 days if you do not use it. You can of course use that credit to call any mobile number in Malaysia at 0.04 Euro or RM 0.18 per minute.

Tested the call to fixed line and found that the quality is good and clear, comparable to that of Skype.
