I use the Google Chrome extension for Google Talk - here's the link - Chat for. As good as google's own standalone-client app that is windows only right now.
One of the other curious things about it is the simplicity that characterizes it. There is no simpler interface for a VoIP app - you have a small, really small when we consider the 27-inch screen of a Mac, window that serves to initiate calls. It has a small window with your and a textbox for entering or selecting the number you want to call.

Upon a call, another window just as small pops up on which you can manage the call. Call management is very basic and you have to use your mouse several times to do so.
You can now configure your app with your SIP address. Enter Account Setup in the app and give your name, the domain of your SIP provider, your username, and password. This information is obtained when you register for a SIP account. The next step is to configure your SIP details.
Select the Network option. Leave the Local SIP Port box empty so it selects a port by itself. Enter your STUN server as obtained from your SIP account. Port 10000 will do. The STUN server is the place where your address finds its public address or is converted into a phone number through which it is recognized in the outside world.
It is, therefore, the point where your SIP provider brings you outside its network to make calls. There is no need to bother with the proxy information if you are using your home connection, but if you are behind a proxy (like for example, when you are at work on a corporate network) ask your network administrator for the necessary information. What does it cost?
You should not be considering the upfront cost of the app, which is very low. Your cost of using it consists mainly of the cost of your calls. This does not depend on the app. It is the price charged by your SIP provider for each minute of call you make, which often depends on the destination number you are calling. Check your provider's site for the rates. It is highly recommended to verify the price before making an international call as. Some countries have very restrictive rates due to their policies regarding VoIP and their level of development.
Telephone has only a handful of features. The most interesting one is that it allows you to make very cheap calls on your computer and to enjoy the. Then there is the app's integration of your address book, which makes it work like it is part of Mac OS itself. The app is quite robust and neat, but being devoid of many features and of an imposing interface makes it free from lags and complications. You can mute calls, hold a call while being on another, transfer a call, and have a call wait while being on another.
