IMPORTANT NOTE: 2N5 Softphone AI is a standalone softphone, not a VoIP service. Making calls requires a SIP server or a subscription with a SIP-based VoIP provider.

IMPORTANT NOTICE REGARDING VOIP ON MOBILE/CELLULAR DATA
Some cellular carriers may prohibit or restrict the use of VoIP functionality on their networks, in addition to applying additional fees or other charges related to VoIP. You agree to acknowledge and respect the restrictions of your cellular carrier's network. 2N5 Tecnologia da Informação e Telecomunicações LTDA will not be responsible for any charges, fees, or possible taxes levied by your carrier for the use of VoIP on mobile/cellular data.

Emergency Calls
The 2N5 Softphone AI offers a service designed to redirect emergency calls to the native cellular dialer whenever possible in the best commercially reasonable manner, although this functionality also depends on the mobile phone's operating system, something beyond our control and subject to change at any time. Therefore, 2N5's official position is that the 2N5 product is not intended for, designed for, or suitable for making or maintaining emergency calls. 2N5 will not be liable for any costs or damages arising directly or indirectly from the use of the software for emergency calls. Using 2N5 Softphone AI as a default dialer may interfere with dialing emergency services.
