sipgate announces the immediate availability of a free application for the iPhone, which, for the first time allows consumers to natively use any VoIP service which uses the industry standard SIP. Consumers can now use their iPhones to make and receive VoIP calls from their devices over a Wi-Fi Internet connection using a wide variety of VoIP providers. The VoIP-enabling software is available from sipgate's website.

With the sipgate service, users can dial any number without using minutes from a wireless plan. This is particularly useful when calling to or from other countries, as call costs can be as high as $3 per minute. However, when using a VoIP service, costs can be kept as low as $0.01 per minute. sipgate is giving new users 111 free minutes for domestic calls for users to test out VoIP usage on the device.

Another benefit of sipgate is that consumers can use any domestic or international number provided by their VoIP service on their iPhone. This means that they can make and receive calls from different domestic and international numbers, all on a single device.
