## Join with a meeting number

Want to join a meeting? The step is simple and easy. First, configure
the meeting parameters `paramDict`:

```objectivec
//For Join a meeting with password
NSDictionary *paramDict = @{
                            kMeetingParam_Username:kSDKUserName,
                            kMeetingParam_MeetingNumber:meetingNo,
                            kMeetingParam_MeetingPassword:pwd,
                            //kMeetingParam_ParticipantID:kParticipantID,
                            //kMeetingParam_WebinarToken:kWebinarToken,
                            //kMeetingParam_NoAudio:@(YES),
                            //kMeetingParam_NoVideo:@(YES),
                            };
//For Join a meeting
NSDictionary *paramDict = @{
                            kMeetingParam_Username:kSDKUserName,
                            kMeetingParam_MeetingNumber:meetingNo,
                            kMeetingParam_MeetingPassword:pwd,
                            };
```

When the parameters are set, then we need to prepare the meeting
parameters that need to pass to the join meeting function:

```objectivec
MobileRTCMeetError ret = [ms joinMeetingWithDictionary:paramDict];
```

## Join meeting status

To know whether the join meeting action is a success or not, or to get
the error message, implement the `onMeetingStatusChange` method.

```objectivec
- (void)onMeetingStateChange:(MobileRTCMeetingState)state;
{
    NSLog(@"onMeetingStateChange:%d", state);

    .....
}
```

## Get the current meeting's available audio types

To get an integer representing the current meeting's supported audio type, call the `getSupportedMeetingAudioType` interface after joining a meeting. The integer value is `bitwise OR` - a bitwise operation - of each supported audio type presented in the `InMeetingSupportAudioType` enum. For example, if the current meeting supports both VOIP and telephony, the return value of `getSupportedMeetingAudioType` for that meeting is `AUDIO_TYPE_VOIP` and `AUDIO_TYPE_TELEPHONY`.
