We are planning a “Call Waiting” feature and will make it available in a future release. ([https://en.wikipedia.org/wiki/Call\_waiting](https://en.wikipedia.org/wiki/Call_waiting))

Until then, your app will need to handle connection states outside of the SDK. Using a group channel with the Chat SDK could be one workaround solution for this.

Connection status will only tell you if they are online or not. It will not tell you if they are in a call or not. However, you can use the Chat SDK to update user metadata (for example: in\_call:true/false) and update it when a call begins/ends. The other users can lookup the user’s metadata before they try to call to know if they are in a call or not.

See:

> **[User Channel Metadata | JavaScript Chat SDK Documentation | Sendbird](https://docs.sendbird.com/javascript/user_channel_metadata#3_user_metadata_4_update)**
>
> With metadata and metacounter which consist of key-value items, you can store additional information to users and channels. This page explains how to manage user metadata, channel metadata, and channel metacounter.

The updated user data will continue to be retrievable via the `sb`. object. The other user metadata is entirely defined by the dictionary you create during the `user.createMetaData()` step.

For example:

```auto
//init
user.createMetaData({in_call:false}, ...);
//start call
user.updateMetaData({in_call:true}, ...);
//end call
user.updateMetaData({in_call:false}, ...);

```

As an alternative, you could create a single group channel for your app that contains all the users that are currently in a call. Invoke `groupChannel.join()` when a call starts, invoke `groupChannel.leave()` when a call ends, and use `groupChannel.members` to get the list of who is currently in a call. With this you can check if the user you are calling is in a call.

> **[Group Channel | JavaScript Chat SDK Documentation | Sendbird](https://docs.sendbird.com/javascript/group_channel#3_retrieve_a_list_of_all_members)**
>
> A group channel is a chat that allows close interactions among a limited number of users. It can be private or public. A private group channel can let a user join the chat through an invitation by another user who is already a member of the chatroom....

Hi @kckern

for the first user enter the call then  
var user = sb.user;  
//init  
user.createMetaData({in\_call:false}, …);  
//start call  
user.updateMetaData({in\_call:true}, …);

Now this time the second user user 2 tries to call user 1

if the user2 loges in and tries this

```auto
var user = sb.currentUser;
var value1 = user.metaData['in_call'];

he get his metadata not the user1 metadata.

how the user2 will get the user1 metadata

////if there any method like this
var user2=sb.getuserbyid(user1);

then get user2 metadata ?
```

Oh, I see what you mean now. To find user2, you will need to use the group channel as described above. `groupChannel.members` will return the user objects of others in the group, from which you can retrieve metadata. User2 will first have to join the group when the call starts. Then user1 can check if user2 is in there.

Can you show the output of `console.log(user)` ?

Can you verify that the `sb` object is from the Chat SDK, not the Calls SDK?

Hi @kckern,

Yes that is the Chat SDK object. The createMetaData method is only available on the currentUser object—can you verify that is the object you are trying to call the method from?

That should work. Can you set a debugger in the code right after console.log(user). Then from the dev tools console, type `user.` (include the dot) and check what functions are available.
