How do I block, view, and unblock phone numbers in Barti?

Who this is for: Any Barti staff member with access to the VoIP section. If you don't see the VoIP menu, contact your Barti administrator.

Before you start, you'll need:

A Barti account with access to the VoIP section

What you'll see when it works

After blocking: The number shows a shield icon in the VoIP call log. Any future call attempts from that number are automatically rejected and logged, and the call attempt count increments each time they try.

After unblocking: The shield icon is removed from the number in the call log, and calls from that number will come through normally.

Troubleshooting

What does the caller hear when they're blocked?

They hear: "Unable to process call at this time. Goodbye."

Does blocking a number also block their texts?

No. Blocking a number only prevents incoming calls. Text messages from blocked numbers are not affected.

Is there a limit to how many numbers I can block?

There is no limit. All blocked numbers and their call attempt history remain visible in the block list table.

I don't see the VoIP menu.

VoIP access is controlled by your Barti administrator. Contact your admin to request access.

Can any staff member block or unblock numbers?

Any staff member with access to the VoIP section can manage blocked numbers.
