Voximplant supports different call endpoints. Phone numbers can be rented from Voximplant or connected via SIP integration. Web, Android, iOS, React Native and Unity SDKs can be used to connect a Voximplant cloud, initiate or accept a call from it. Connected SDKs are authorized with “Voximplant users” which can be created manually via the control panel or programmatically via the HTTP API. SDKs can also forward custom data while initiating or accepting a call and use advanced “messaging” functionality to communicate with each other. Voximplant supports incoming and outgoing SIP calls to integrate with third-party telephony and handle SIP phones or SIP software.
