VoIP Clients – a Variety of Choices

Ever since the iPhone revolutionized mobile calling with its awesome feature set and powerful application driven framework, there's been no shortage of innovative apps that implement the SIP protocol to provide VoIP calls. Indeed, many other Internet calling applications such as Viber have also sprung up to fill the need for cheap communication between individuals. As a result, customers have been spoiled for choice on both the iPhone and the Android platforms. While a few great applications like Bria for Android and iOS are paid, many of them are free to use and a few outstanding software programs like CSipSimple have led the way in offering a huge number of configuration options as well as deep integration with a great number of well-known SIP providers.

All this variety means that customers have to make a decision as to what SIP client they should use. Because VoIP is not standardized in every aspect, many SIP clients require special configurations to work with different SIP providers. How can first time VoIP users get around this hassle and ensure that their VoIP experience is as seamless as possible? In truth despite the large number of configurable SIP clients available, customers might will be better off using an SIP application that is provided to them by their ITSP instead.

Easy VoIP Configuration

Despite all the progress made on the VoIP front, SIP VoIP is not exactly plug-and-play yet. Many SIP providers interface with VoIP clients in different ways requiring special considerations for proper interoperability. These include codecs, SIP forking, support for secure RTP, TCP, and a plethora of other parameters that might or might not work with a given provider. Many ITSP's have a page that describes the configuration options that must be set for most of the popular SIP clients around. This helps first-time users to understand what they need to fill up.

There's no doubt however that having an application that is directly provided to you by your SIP provider is the best option for first-time users. You might not get a lot of flexibility and you will almost certainly not be able to use it with any other VoIP provider, but setting it up will be a snap and you won't face any configuration issues. VoIP on the iPhone and Android platforms is best used with a Wi-Fi connection rather than a 3G or 4G one. this is because Wi-Fi is still the most reliable wireless Internet connection that people have easy access to.

Contact your Internet telephony service provider to find out whether or not they offer an SIP client of their own and if not, which client they recommend and what website you can use to find out the correct configuration options with screenshots.
