Some mobile network operators may prohibit or restrict the use of VoIP functionality over their network and may also impose additional fees, or other charges in connection with VoIP.

Emergency Calls

Lightning Telecom's mobile products provide handling designed to redirect emergency calls to the Native Cellular Dialer when possible on a best reasonable commercial efforts basis, however this functionality is also dependent on the operating system of the mobile phone which is outside of our control and subject to change at any time. As a result, the official position of Lightning Telecom is that the Lightning Telecom product is not intended, designed, or fit for placing, carrying or supporting Emergency Calls. Lightning Telecom will not be liable for any costs or damages arising either directly or indirectly from the use of the software for Emergency Calls.
