Config for IOS

iOS(Object-C):

Assets: Add call_image into assets folder to update callkit image. We only support png style.
Add variables in Appdelegate.h for Old Architecture:

#import <UIKit/UIKit.h>
#import <UserNotifications/UserNotifications.h>
#import <OmiKit/OmiKit-umbrella.h>
#import <OmiKit/Constants.h>

@interface AppDelegate : UIResponder <UIApplicationDelegate, RCTBridgeDelegate, UNUserNotificationCenterDelegate>

@property (nonatomic, strong) UIWindow *window;
@property (nonatomic, strong) PushKitManager *pushkitManager;
@property (nonatomic, strong) CallKitProviderDelegate * provider;
@property (nonatomic, strong) PKPushRegistry * voipRegistry;

@end

Add variables in Appdelegate.h for New Architecture:

#import <UIKit/UIKit.h>
#import <UserNotifications/UserNotifications.h>
#import <OmiKit/OmiKit-umbrella.h>
#import <OmiKit/Constants.h>

@interface AppDelegate :  NSObject <UIApplicationDelegate, UNUserNotificationCenterDelegate, RCTBridgeDelegate>

Add these lines into Info.plist:

<key>NSMicrophoneUsageDescription</key>
<string>Need microphone access for make Call</string>
//If you implement video call
<key>NSCameraUsageDescription</key>
<string>Need camera access for video call functions</string>

Save token for OmiClient: if You added Cloud Messaging in your project so you don't need add these lines.

- (void)application:(UIApplication*)app didRegisterForRemoteNotificationsWithDeviceToken:(NSData*)devToken
{
    // parse token bytes to string
    const char *data = [devToken bytes];
    NSMutableString *token = [NSMutableString string];
    for (NSUInteger i = 0; i < [devToken length]; i++)

    }

    // print the token in the console.
    NSLog(@"Push Notification Token: %@", [token copy]);
    [OmiClient setUserPushNotificationToken:[token copy]];
}

Only use under lines when added Cloud Messaging plugin in your project

Setup push notification: We only support Firebase for push notification.

Important release note

We support 2 environments. So you need set correct key in Appdelegate.
- KEY_OMI_APP_ENVIROMENT_SANDBOX support on debug mode
- KEY_OMI_APP_ENVIROMENT_PRODUCTION support on release mode
- Visit on web admin to select correct enviroment.

*Note: At Tab Build Setting off Target Project, you need set: Enable Modules (C and Objective C) : YES*

iOS(Swift):

Assets: Add call_image into assets folder to update callkit image. We only support png style.
Add variables in Appdelegate.swift:

import OmiKit
import PushKit
import NotificationCenter

var pushkitManager: PushKitManager?
var provider: CallKitProviderDelegate?
var voipRegistry: PKPushRegistry?

Add these lines into didFinishLaunchingWithOptions:

OmiClient.setEnviroment(KEY_OMI_APP_ENVIROMENT_SANDBOX, userNameKey: "extension", maxCall: 1, callKitImage: "call_image")
provider = CallKitProviderDelegate.init(callManager: OMISIPLib.sharedInstance().callManager)
voipRegistry = PKPushRegistry.init(queue: .main)
pushkitManager = PushKitManager.init(voipRegistry: voipRegistry)

Add these lines into Info.plist:

<key>NSCameraUsageDescription</key>
<string>Need camera access for video call functions</string>
<key>NSMicrophoneUsageDescription</key>
<string>Need microphone access for make Call</string>

Save token for OmiClient: if you added firebase_messaging in your project so you don't need add these lines.

func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
    let deviceTokenString = deviceToken.hexString
    OmiClient.setUserPushNotificationToken(deviceTokenString)
}

extension Data {
    var hexString: String {
        let hexString = map { String(format: "%02.2hhx", $0) }.joined()
        return hexString
    }
}

Implement

Request permission

We need you request permission about call before make call:

You can use react-native-permissions to do this

-Android: 
+ PERMISSIONS.ANDROID.RECORD_AUDIO
+ PERMISSIONS.ANDROID.CALL_PHONE
+ PERMISSIONS.ANDROID.CAMERA; (if you want to make Video calls)

-IOS:
+ PERMISSIONS.IOS.MICROPHONE;
+ PERMISSIONS.IOS.CAMERA; (if you want to make Video calls)

Set up Cloud Messaging plugin:

//if you use only on Android. you only implement for Android.
//because we use APNS to push notification on iOS so you don't need add Firebase for iOS.
//But you can use firebase-messaging to get APNS token for iOS.

Important function.
- Start Serivce: OmiKit need start services and register some events.
```
//Call in the root widget
import { startServices } from 'omikit-plugin';

startServices();
```
- OmiKit need FCM for Android and APNS to push notification on user devices. We use more packages: Cloud Messaging
- Create OmiKit With ApiKey: OmiKit need apikey, username, user id to init environment(All information in innit is required). ViHAT Group will provide api key for you. This function is used when making calls from customers to switchboard numbers (not making internal calls). Please contact for my sale: In This step, we need partner provide me fcmToken of firebase Message.
```
import { initCallWithApiKey } from 'omikit-plugin';
import messaging from '@react-native-firebase/messaging';

let token: String 
if(Platform.OS == "ios"){
  token = await messaging.getAPNSToken()
} else {
  token = await messaging.getToken()
}

const loginInfo = {
  usrUuid: usrUuid,
  fullName: fullName,
  apiKey: apiKey,
  phone: phone,
  fcmToken: token,  //with android is fcm_token and ios is APNS token
  isVideo: isVideo,
};
const result = await initCallWithApiKey(loginInfo);
//result is true then user login successfully.
```
- Create OmiKit: OmiKit need userName, password, realm, fcmToken to init environment(All information in innit is required). ViHAT Group will provide information for you. This function is used when you want to call any telecommunication number, calling back and forth between internal groups. Please contact for my sale:

    import { initCallWithUserPassword } from 'omikit-plugin';
    import messaging from '@react-native-firebase/messaging';
    
    let token: String 
    if(Platform.OS == "ios"){
      token = await messaging.getAPNSToken()
    } else {
      token = await messaging.getToken()
    }

    const loginInfo = {
      userName: userName, //string
      password: password, //string
      realm: realm, //string
      isVideo: isVideo, //boolean: true/false
      fcmToken: token, //with android is fcm_token and ios is APNS token
    };
    const result = await initCallWithUserPassword(loginInfo);
    //result is true then user login successfully.

Config push notification:

import { configPushNotification } from 'omikit-plugin';

configPushNotification({
  notificationIcon : "calling_face", //notification icon on Android
  prefix : "Cuộc gọi tới từ: ",
  incomingBackgroundColor : "#FFFFFFFF",
  incomingAcceptButtonImage : "join_call", //image name
  incomingDeclineButtonImage : "hangup", //image name
  backImage : "ic_back", //image name: icon of back button
  userImage : "calling_face", //image name: icon of user default
  prefixMissedCallMessage: 'Cuộc gọi nhỡ từ', //config prefix message for the missed call
  missedCallTitle: 'Cuộc gọi nhỡ', //config title for the missed call
  userNameKey: 'uuid', //we have 3 values: uuid, full_name, extension.
  channelId: 'com.channel.sample', //your notification channel id
  audioNotificationDescription: '' //audio description
  videoNotificationDescription: '' //video descriptipn
});
//incomingAcceptButtonImage, incomingDeclineButtonImage, backImage, userImage: Add these into `android/app/src/main/res/drawble`

Get call when user open application at first time:

import { getInitialCall } from 'omikit-plugin';

const callingInfo = await getInitialCall();
if (callingInfo !== false) {
  navigation.navigate('DialCall' as never, callingInfo as never);
}
//callingInfo != false then user have a calling.

Other functions:

Call with phone number (mobile phone or internal number):

import {startCall} from 'omikit-plugin';
const result = await startCall({
    phoneNumber: phone, //phone number
    isVideo: false //allow video call: true/false
});

The result will be in the form of object:

result = {
    "_id": String // This is call_id. it just have id for iOS,
    "status": Number // This is result code when make,
    "message": String // This is a string key, describing the status of the call
  }

Describe in detail the results when startCall returns:

  + message="INVALID_UUID" (status = 0) : uid is invalid (we can not find on my page).
  + message="INVALID_PHONE_NUMBER" (status = 1) : sip user is invalid.
  + message="SAME_PHONE_NUMBER_WITH_PHONE_REGISTER" (status = 2) :  Can not call same phone number.
  + message="MAX_RETRY" (status = 3) : call timeout exceeded, please try again later.
  + message="PERMISSION_DENIED" (status = 4) : The user has not granted MIC or audio permissions.
  + message="COULD_NOT_FIND_END_POINT" (status = 5) : Please login before make your call.
  + message="REGISTER_ACCOUNT_FAIL" (status = 6) : Can't log in to OMI( maybe wrong login information).
  + message="START_CALL_FAIL" (status = 7) : Call failed, please try again
  + message="HAVE_ANOTHER_CALL" (status = 9) : There is another call in progress, please wait for that call to end
  + message="START_CALL_SUCCESS" (status = 8) : START CALL SUCCESSFULLY.

Call with UUID (only support with Api key):

import {startCallWithUuid} from 'omikit-plugin';
const result = await startCallWithUuid({
    usrUuid: uuid, //phone number
    isVideo: false //allow video call: true/false
});
// Result is the same with startCall

Accept a call:

import {joinCall} from 'omikit-plugin';

await joinCall();

End a call: We will push a event endCall for you.

import {endCall} from 'omikit-plugin';

const value = await endCall();
//value is call information
Sample output:
{
   "transaction_id":ea7dff38-cb1e-483d-8576...........,
   "direction":"inbound",
   "source_number":111,
