Most of the apps categories in Google Play Store are overcrowded by thousands of apps vying for attention but there are a few exceptions too. Voice/Video chatting (voice calling over internet)
 is one such category which has a very limited number of apps. And out 
of these apps (which have this special function – allowing users to 
actually “chat”), only a selected few are up to the mark in terms of 
voice calling quality and hassle-free performance. Voice calling over 
internet is just like network dependent phone calling, provided you have
 a reasonably fast internet connection (which most of us have these 
days). The only catch in these apps is that the app must be installed on
 both ends (caller and receiver) and both devices must be connected to 
internet for free calling. Anyway here are the top 9 apps for voice calling (over internet) on an Android phone/tablet –
Skype
 – is perhaps the most popular app in this category which allows you to 
make free voice and video calls (Skype to Skype) and cheap international
 mobile calls (Skype to any number). The best part of Skype is that its a
 cross platform app available for almost all mobile and desktop OS. You 
can get Skype free from Google Play
Official Google Voice app
 – Google Voice for Android is an impressive app with which you can send
 free text messages and make voice calls all over the world. Download 
Google Voice free from Play Store
Line
 – Line is a relatively new entry in this category but in a short time 
it has become hugely popular especially among youngsters. Line has a 
feature-set almost similar to WhatsApp and WeChat plus the added 
advantage of free voice calling. Download Line free from Play Store
Viber
 – Viber is a popular, cross-platform messenger app allowing users to 
send free text messages, video messages and to make voice calls. You can
 get Viber from Google Play
Fring – Besides text chatting, Fring also allows free group voice calling (upto four persons at a time). Download from Google Play
Tango – Tango supports group voice calling (upto 50 persons) and video calling at a time. Get Tango from Google Play
ooVoo
 – is a video chatting app supporting voice and video calls (upto 12 
persons at a time), photo and video sharing, text messaging. Download 
from Google Play
ICQ – ICQ is a messenger app which also supports voice chatting. Download ICQ from Google Play
Kakao Talk
 – KakaoTalk is another WhatsApp alternative app supporting group chat, 
voice calling and photo/video/voice message sharing. Download from Google Play
So what’s your pick out of these? and do add any other app you know in this category which I missed here.
