Sipgate, stylised as sipgate, is a European VoIP and mobile telephony operator.
Sipgate was founded in 2004 and became one of Germany's largest VoIP service providers for consumers and small businesses. Through its network, which used SIP protocol, it allowed making low-cost national and international calls and provided customers with an incoming geographical phone number.

Smartphone apps
Sipgate provided a software application called sipgate for use with Apple iOS and Android devices. In September 2008, the Higher Regional Court of Hamburg (Germany) sided with a request by T-Mobile and issued an injunction preventing the download of sipgate, barring iPhone owners from placing calls over the device's Internet connection rather than over T-Mobile's cellphone network. In counter action, Sipgate won an injunction against T-Mobile to bar it from advertising unlimited Internet access via the device. [9] In March 2013 support and further development of the smartphone VoIP apps was ceased.

A telephone call or telephone conversation, also known as a phone call or voice call, is a connection over a telephone network between the called party and the calling party. Telephone calls started in the late 19th century.

Telephone calls are typically used for real-time conversation between two or more parties, especially when the parties cannot meet in person.

Often, a softphone is designed to behave like a traditional telephone, sometimes appearing as an image of a handset, with a display panel and buttons with which the user can interact. A softphone is usually used with a headset connected to the sound card of the PC or with a USB phone.

This sort of spoofing is common for calls originating from voice-over-IP (VoIP) systems, which can be located anywhere in the world.
