Hi everyone,

We’ve upgraded to the latest version of Wazo; 19.15.  
One issue that we’re coming across is that there’s no ring back when somebody calls us. They just get silence until we answer the call.

In the past, we’ve been told that this is because we have “Music on Hold” set to something under Ring Groups. The issue is that the new UI does NOT allow us to blank out this option. In other words, a blank is not an option for the dropdown so it seems to be impossible to correct this.

Would anybody have an idea?

I’m bumping this up to see if there was any solution?

Hi,

you’re right, it’s a bug. It should be possible to remove the music on hold from a ring group

Hi,  
Was there a fix to this?  
Callers don’t get a ring back and think our phone lines are down…

Hello heatmap,

The fix will be included in about a month.  
Meanwhile, you can do it via the API.

On your engine, create a token using wazo-auth-cli for your root user, like this:

```auto
wazo-auth-cli token create --auth-username root --auth-password <yourpassword>

```

Then, go to `http://<your_ip>/api/`, paste the token `wazo-auth-cli` gave you in the token textbox at the top right of the page and navigate to the wazo-confd API from the menu on the left.

Navigate to the `groups` section, click on it and find the `PUT /groups/{group_id}` endpoint.

Then, take the ID from the URL of the group you want to change from wazo-ui (i.e https://\<your\_ip\>/engine/groups/ **ID**?bc\_names[]=Groups&bc\_urls[]=%2Fengine%2Fgroups%2F&bc\_icons[]=users) and copy-paste the ID in the `group_id` field of the API page.  
Then you want the following body:

```auto
{
  "music_on_hold": null
}

```

Click on the `Try it out` button and you should get a `no content` `204` response.

If you have any issue please let me know.

Thank you!

Thank you so much for the tip.  
When I go to [http://192.168.1.187/api/](http://192.168.1.187/api/) and enter in the token it gives me the message:  
`failed to parse JSON/YAML response`  
When I click on the wazo-confd link and then enter in the token, it gives me the message:  
`Can't read from server. It may not have the appropriate access-control-origin settings.`

This seems to be a CORS error. I was able to do this with Safari which doesn’t give the same error.

Thank you so much for your help.

Hello heatmap,

I forgot to tell you! Please open the link to the wazo-confd API in a new tab and accept the certificate. wazo uses a self-signed certificate internally.

Thank you!
