UPDATED : CSipSimple just released 0.00-12-24 today (2010-AUG-28). A quick test is conducted and some bugs are fixed. This tutorial will be updated when I fully tested this new version.
UPDATED : The current version is 0.00-12-36 as on today (2010-SEP-22). The app is much more stable.
This tutorial is show you how to setup your Android phone to communicate with another IP Phone or Android in no further investment. Meanwhile, this feature does not consume your mobile phone air time but consume the 3G data. If you have an unlimited 3G plan, you will be very happy with that. Make sure you are connected to the internet when using the VoIP. Wifi also works fine.

The following SIP providers offer free account of SIP service for inbound and outbound. You can select one of them that suit you most. I prefer
sip2sip.info. Make sure to register to the SIP provider and write down all the details that they give you for further setting.
For example, your login name (account name) of sip2sip.info is "
PART II - Asterisk configuration
If you have an Asterisk server, you can set it yourself. The settings are similar to the below mentioned.

You will have 2 simultaneous calls, 5 trunks and 5 extensions per account.

PART VI - Conclusion
Although SIPDroid is the first apps in the Market for VoIP and it also provides video streaming, the dial out procedure is not mature. The apps cannot running in the background for awaiting VoIP calls when you always dial out to PSTN (land lines). It is because it dial out VoIP calls only.
CSipSimple is still in alpha stage but it is quiet more stable as at 0.00-12-22. You can select if you want to dial out via SIP account or Mobile phone number. It is quiet mature. It will be prefect if it also provide video streaming and contact list for VoIP dial out.
CSipSimple and SIPDroid are working prefectly on Asterisk.
The current development version (CSipSimple 0.00-12.22) does not support bluetooth. When bluetooth is enabled, the incoming and outgoing call may caused your Android hang or power off is required.
This tutorial may also apply to other smartphones or desktops that have SIP Client. For Ubuntu or Linux, you can use
That's all! See you.
