Making calls via SIP registration

VoxImplant supports forwarding calls to 3rd party SIP server using VoxEngine’s callSIP method which is rather complicated and requires knowledge of SIP protocol. VoxImplant supports SIP Registrations – it registers on 3rd party SIP server as a client and can make/receive calls using the client account, now it’s possible to make outbound calls using SIP registrations in the following way:

var call = VoxEngine.callSIP("some_number", { regId: SIP_REGISTRATION_ID });


SIP_REGISTRATION_ID can be found in SIP Registrations section of the control panel or using HTTP API

Inbound calls that come from SIP Registration arrive to VoxEngine scenario as any other call resulting in CallEvents.Alerting event dispatch.
