 # Handling Calls With UI using **Reve** Voice SDK  
  
- After calling the `SIPWrapper.startSIP()` method VOIP Calling is available to you through `CallHandler.makeCall()` and other similar methods. 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](Configuring-Listeners) to correctly Implement Listeners.

- After Listeners are correctly implemented you can use your UI to start your calls with ```CallHandler.makeCall(phoneNumber:String)``` function can be called and the you can get the relevant call related info through the Listeners.
+ After Listeners are correctly implemented you can use your UI to start your calls with the method
+ ```kotlin
+ 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 `callHandler.endCall()` method.
+ After you have started a call with makeCall method, you can end this call by invoking the the following method
+ ```kotlin
+ CallHandler.endCall()
+ ```
+
+Finally you can accept incoming calls by invoking the method
+```kotlin
+callHandler.acceptCall(callID)
+ ```
+You can find the callID through the **SDKServiceListener** *(See [Listeners Guide](Configuring-Listeners))*
+
+#### In call Functionalities
+While a call is going on three features of calls can also be found in this SDK.
+You can 
+1. Mute your Microphone,
+2. Hold your Call &
+3. Turn on the Speaker.
+You can use the following methods to achieve the aforementioned call features.
+
+
+To mute call 
+```kotlin
+CallHandler.setCallMute(true)
+```
+To unmute call
+
+```kotlin
+CallHandler.setCallMute(false)
+```
+
+
+
+To hold call 
+```kotlin
+CallHandler.holdCall(true)
+```
+To unhold call
+
+```kotlin
+CallHandler.holdCall(false)
+```
+
+To turn on speaker 
+```kotlin
+CallHandler.setSpeakerOn(true)
+```
+To turn off speaker
+
+```kotlin
+CallHandler.setSpeakerOn(false)
+```
+
+<!-- #### Incoming calls
+You can get the incoming call id from `ListenersProvider.sdkServiceListener` Then you can invoke callHandler.acceptCall(callId) to accept the current incoming call. -->
 
- Finally you can accept incoming calls by invoking `callHandler.acceptCall(callID)` method. You can find the callID through the **SDKServiceListener** *(See [Listeners Guide](Configuring-Listeners))*
