# Two-Way Audio Settings

## About MiCollab AWV Two-Way Audio

As a MiCollab user in Audio, Web and Video conference (AWV), with the introduction of the feature of two-way audio mode, the user can use the AWV web client for two-way audio functionality, similar to an AWV desktop client.

This topic provides instructions on how to integrate and configure the two-way audio feature with the supported PBXs.

## Two-Way Audio Integration

The user will see the two-way audio option in AWV web client if the feature is configured on the MiCollab server and if the WebRTC supported browsers and operating systems are used. AWV web client uses MiVoice Border Gateway (MBG) anonymous call WebRTC capability.

Two-way audio integration with MiCollab is a three-step process:

- AWV Configuration

- MBG Configuration

- PBX Configuration

Note: The supported platforms for two-way audio are MiVoice Business, MiVoice 5000, and MX-One.

Note: The two-way audio on MX-One is supported only on Standalone MBG.

Note: The MBG WebRTC settings should be configured on AWV for the two-way audio to work.

Note: MBG should be provisioned with an additional RAM and CPU for proper functioning of two-way audio WebRTC calls. For more information on memory and CPU usage, see MiCollab Engineering Guidelines > MiVoice Border Gateway Guidelines section.

#### Requirements for Two-Way Audio from the Web Client

Component | Requirement
Mobile Device Operating System | Android (Mobile/Tablets)
Web Browser | Mozilla Firefox® Standard Release 43 or higher Google Chrome™ 47 or higher
Operating System | Windows 7,8 and 10 Mac™
Devices | Surface Pro

## To Enable Two-Way Audio

#### 1. AWV Configuration

Configure the following fields for MBG WebRTC Settings under Server Manager > Audio, Web and Video Conferencing > Configuration > Two-Way Audio Settings.

- MBG Server Name - Enter the name of the MBG server.

- MBG WebRTC Port - Enter the port number of WebRTC. The default value of MBG WebRTC port is 5063.

- Web Server Shared Secret - This value should be same as the WebRTC value for MBG configuration.

- SIP URI - Enter the SIP URI details from the MiVoice 5000 PBX configuration. Note that this field is case sensitive. This field is visible only when MiVoice 5000 is selected.

Note: The AWV hunt group number of PBX should be configured under Dial-In Phone Number 1 field which is present in system options of AWV admin portal.

To view and update the MBG WebRTC settings, see Server Manager > MiVoice Border Gateway > Teleworking > WebRTC.

#### 2. MBG Configuration

Log in to MiCollab Server Manager and navigate to MiVoice Border Gateway >Teleworking >WebRTC.

1. Select the Enabled checkbox to enable the WebRTC Service.

2. Under Licenses, make sure you have active Anonymous calls licenses. If this value is “0” then purchase the following license from AMC and sync MiCollab licenses.
   “MBG: 1 SIP Trunking Channel License”.

3. Change the Hosting mode to anonymous and subscriber.

4. Configure the Webserver shared secret password.

5. Click Save

For detailed description of WebRTC settings, see Configuration > WebRTC section in the MBG online help document.

## Troubleshooting

Scenarios for AWV Web Client errors

Sl No | AWV WebClient Error Messages Reported by User | Possible correction steps for Admin/User
1 | Failed to reach MBG audio gateway. Please check your network connection and try again. If problem persists, contact the administrator. | The user should check the network connection, which should be in working condition and stable. MBG FQDN and PORT should be accessible from the user's system The administrator should check if the MBG FQDN and PORT configured in MBG WebRTC settings are correct.
2 | MBG audio gateway authentication has failed, please contact the administrator. | The Web Server shared secret provided in MBG WebRTC Settings isn’t valid. To retrieve the currently used Webserver shared secret key, go to Admin Portal>MBG>Teleworking>WebRTC>Download SDK. Extract the downloaded file, open config.php file, look for $websocket_passphrase entry. The value against it is the secret key. Use this key for configuring MBG WebRTC in AWV. Admin can set a new secret key in Admin Portal>MBG>Teleworking>WebRTC, and use that in MBG WebRTC in AWV.
3 | Failed to establish connection with MBG audio gateway. Please try again. If problem persists, contact the administrator. | In case of this error, the user should download the Web Client logs from, More > Web Client Logs, and share it with the support team.
4 | An error occurred while joining the audio. Please refresh your browser and try again. If problem persists, contact administrator. | If refreshing the browser doesn't resolve the issue then Web Client logs should be downloaded from, More > Web Client Logs, and shared with the support team.
5 | No audio device detected on system. Please check your system audio settings and try again. | User needs to attach an audio device to the system and recheck. If audio device is already attached to the system, then user needs to check and configure it in System Audio Setting.
6 | User reports about audio getting silent in an on-going call | User needs to reconnect the audio call. If that doesn't work then refresh the Web Client. If the user is continuously facing this issue, the AWV Web client logs should be collected and shared with the support team.
