Inbound traffic means traffic coming from Viber mobile application users towards the business. The following scenarios are all supported:

Context	Scenario	Description
Viber end users calling your contact center	Viber calls to Conversations	Incoming calls from Viber users to the Viber Business Calls number will be redirected to Conversations. How to implement: Set up call forwarding from your Viber Voice number towards Conversations. Start from step 2 under Configure channels / Set up Calls. Your Viber number is listed as a "Dedicated Viber Voice" number under the Voice channel application on the web interface.
Viber end users calling your contact center	Viber calls to Conversations with Moments (Flow)	Incoming calls from Viber users to the Viber Business Calls number will be redirected to an IVR created with Flow in Infobip Moments. If needed, this Flow can transfer this incoming call to Conversations or to any external regular phone number. How to implement: Select your Viber Voice number in the Start incoming call trigger of the Flow you are creating to implement your IVR scenario.
Viber end users calling your IVR	Viber calls to Moments (Flow)	Incoming calls from Viber users to the Viber Business Calls number will be redirected to an IVR created with Flow in Moments.

How to implement: Select your Viber Voice number in the Start incoming call trigger of the Flow you are creating to implement your IVR scenario.
Viber end users calling your IVR	Viber calls to IVR (API)	Incoming calls from Viber users to the Viber Business Calls number will be redirected to an IVR created with the IVR API. This IVR can forward the call to an external PSTN number. How to implement: Create your IVR scenario with the Create a Voice IVR Scenario method, keep the returned `scenarioId`. Retrieve the `numberKey` for your Viber voice number. Create a voice setup for this Viber voice number, using the action type `FORWARD_TO_IVR` and using both `numberKey` and `scenarioId` from the previous steps.
Viber end user calls are redirected to your regular phone number	Viber calls to PSTN	Incoming calls from Viber users to your Viber Business Calls number will be redirected to a predefined external fixed or mobile phone number. This can allow Viber end users to reach a business on their regular phone number but calling at no cost (for the end user). How to implement: For simple forwarding scenarios to a single phone number, simply setup Forward to phone action on the Viber Voice number. For advanced forwarding scenarios including failover numbers, define your route in Infobip call routing and setup the Forward to call routing action on your Viber voice number.
Viber end user calls are redirected to your telephony system	Viber calls to SIP Trunking	Incoming calls from Viber users to the Viber Business Calls number will be redirected to your telephony equipment (SBC, PBX) over SIP Trunking. This can allow Viber end users to reach a business on their regular phone environment but calling at no cost (for the end user). How to implement: Have a least one SIP trunk defined towards your SIP equipment. Define a route in the Infobip Call Routing application, that includes at least one of your SIP trunks. Simply setup Forward to call routing action on the Viber Voice number.
Viber end user calls are redirected to your web or mobile application	Viber calls to webRTC	Incoming calls from Viber users to your Viber Business Calls number will be redirected to a predefined webRTC user in the web or mobile application you developed based on the Infobip webRTC SDKs. This can allow Viber end users to reach a business in their voice enabled application but calling at no cost (for the end user). How to implement: Define a route in Infobip Call Routing that includes at least one webRTC destination and setup the Forward to call routing action on your Viber voice number.
Build your own voice inbound scenario	Viber calls to the custom voice application of the customer, built on top of Calls API	Incoming calls from Viber users to the Viber Voice number of the customer will be redirected to the custom voice application that the customer has developed (and hosts) based on the Infobip Calls API platform. How to implement: Retrieve the `numberKey` for your Viber voice number. Create a Voice setup to associate the `numberKey` of this Viber Voice number to your `applicationId`. The action type is `FORWARD_TO_SUBSCRIPTION`. See the inbound call flow documentation of Calls API for complete guidance on these steps.
