Handling Calls With UI using Reve Voice SDK

After calling the SIPWrapper.startSIP() method VOIP Calling is available to you through the method

CallHandler.makeCall()

But Even if you have access to the call functionalites, you need to Make your UI work according to the background tasks. The Listeners Interfaces SDKSIPListener and SDKServiceListener are used for that reason. See Listeners Guide to correctly Implement Listeners.

After Listeners are correctly implemented you can use your UI to start your calls with the method

CallHandler.makeCall(phoneNumber:String) 

This method can be called and the you can get the relevant call related info through the Listeners.

After you have started a call with makeCall method, you can end this call by invoking the the following method

CallHandler.endCall()

Finally you can accept incoming calls by invoking the method

callHandler.acceptCall(callID)

You can find the callID through the SDKServiceListener (See Listeners Guide)
