Can I permanently block a number?

This is possible through the blocking numbers option in your carrier.

The same will be done by blocking an app with carrier.

Can I add my contacts to the auto answer option? As a default most VoIP apps have an auto answer function; this function will forward your VoIP request to your contact automatically, without any dialog. If you want to add more contacts to this function you can simply add contacts in your contacts list or use a program that enables you to do so. In all cases VoIP will forward the request for the contact to the last contact added in auto answer setting.

I have some problems with the VoIP connection, why is it like this?VoIP is like a typical telephone network connection, where one terminal will receive speech at the other terminal. Because two points are in a line it will have several problems and sometimes there might be very long delay one side of the line (if it's a local problem you might be located near to someone with similar internet connection). It can also happen that there is just very few minutes of data in each package of the user's internet access and you have just limited free phone voice minutes per month on the same plan. VoIP does not like such conditions very well. I recommend having unlimited phone minutes per month and if you are really struggling with the quality of your VoIP calling, consider switching service provider, switch to a VoIP that has higher quality, switch to a VoIP service that offers the VoIP call rates with a free option (that's also cheaper than a prepaid plan), go prepaid and use a VoIP service that has unlimited free phone calling in Europe but no free calls to North America or some other parts of the world (and if you travel to these places very often, it's good if you have a prepaid option), etc.

Can I buy phone minutes through a VoIP?VoIP works like a conventional phone network and phone minutes are bought and used in it exactly like you used regular phone minutes before, except that you won't use conventional phone minutes because you'll use data (and most likely high-quality VoIP minutes on the VoIP platform, because data packages have low quality). So you need to choose between phone minutes and data (or high quality phone minutes if you prefer to have them when calling other clients).

I would like to start my personal business by offering VoIP, what tools do I need?

How to permanently block a number on Android Samsung?

I assume that you want to block calls from particular number on your Samsung device.

Please read my answer here about blocking contacts: How to block certain contacts from calling on android? But in your case, you need to use a different approach. You need to intercept the outgoing calls with the intent filter: . . . This should be part of your app's receiver activity and not of system receiver (ie receiver of system services). The last part, the will be matched only by an app that supports this action and sends it to the app's default handler.

In your app's Activity, you should intercept the call with the code like this: public class CallInterceptor extends Activity implements OnCallStateChangedListener );. method.
