Discontinued products

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. In March 2013 support and further development of the smartphone VoIP apps was ceased.

Services in United States and Austria

Sipgate operated a subsidiary which provided sipgate-branded VoIP services in Austria and the US. On 31 December 2013, the company discontinued Austrian operations citing negative regulatory restrictions imposed by the Austrian telecommunications regulator RTR. The RTR imposed rulings that a company can only supply a telephone number to a property if they also supply the associated cabling.

All services provided by Sipgate Inc (USA) were discontinued as of 31 October 2013.

sipgate one

sipgate one was a product that allocated the customers a German mobile number and incoming calls were then forwarded to customer's landline number or Skype. The service was discontinued on 31 July 2013.
