The fixes for the call problems we see most often.

## "Call Failed" when dialling from the desktop app

**The cause (nearly every time):** the app defaults to using a *desk phone* as its calling device. If you don't have a physical desk phone registered on your extension, every call fails.

**The fix:**

1. Open the phone dialler in the Communicator app
2. Look at the device selector in the lower-right corner — it likely says **Deskphone**
3. Click it and choose **Softphone**
4. Accept the prompt and make a test call

## Calls from private/withheld numbers ignore my call forwarding

If calls from "No Caller ID" numbers don't follow your forwarding rules, your extension is missing a Caller ID assignment. This one needs a quick change on our side — [raise a ticket](https://jabblefish.ai/ticket/) with the extension number and we'll set it.

## I can't find the Central Phone Book in the desktop app

It moved in a recent version. It's now under: **Home tab → Contacts → Central Phonebook**.

## Checking your own audio

Dial **\*398** for an echo test — you'll hear your own voice played back. If the echo is clear, your microphone, speaker and connection to us are all fine, and the problem is likely on the far end.

## Voicemail from someone else's desk

Dial **\*124**, then enter the mailbox's extension number and its PIN. Handy when you're covering a colleague's phone.

## Still stuck?

Chat with us via the bubble, or [raise a ticket](https://jabblefish.ai/ticket/) with: the extension affected, an example call (time + number), and what happened vs. what you expected. We'll take it from there.
