Phone Number, Business Hours & Call Screening

What it does

These three settings control when your AI receptionist answers calls, which phone number it answers on, how callers reach it, and whether robocalls get screened out automatically.

• Phone — shows your Azumo number and step-by-step instructions for forwarding your existing business line to it.
• Business Hours — sets the schedule your receptionist works. Outside those hours it can take a message or play a closed message, depending on your preference.
• Call Screening — filters out robocalls and lets you block specific phone numbers permanently.

How to get there

In the left sidebar, click Settings. The phone-related settings are split across three tabs:

Step-by-step

Phone tab

Finding your Azumo number

Your AI receptionist’s phone number is displayed at the top of the Phone tab in large text. This is the number that Azumo answers — it is the number you will forward your existing business line to.

If the page shows “No phone assigned yet — contact customer support”, your number has not been provisioned yet. This is handled by your Azumo administrator during setup. Reach out to support@azumo.com and they will assign a number to your account.

Setting up call forwarding

Once you have an Azumo number, you need to tell your phone carrier to send incoming calls there. The Phone tab shows step-by-step instructions for the five most common carriers. Click the tab for your carrier and follow the steps shown:

• AT&T — dial *21* followed by your Azumo number from your AT&T phone
• Verizon — use the forwarding code shown on the Verizon tab
• T-Mobile — use the forwarding code shown on the T-Mobile tab
• Google Voice — go to your Google Voice settings and enter your Azumo number as the forwarding destination
• RingCentral — go to your RingCentral admin portal and configure call forwarding to your Azumo number

After forwarding is active, callers dial your existing business number as usual and your AI receptionist answers — they will never know the call was forwarded.

Business Hours tab

Always Available (24/7)

Select Always Available (24/7) if you want your receptionist to answer every call at any hour. This is the default setting. Your receptionist will try to reach contacts and take messages around the clock.

Set a Schedule

Select Set a Schedule to define which hours your receptionist is “open.” A weekly grid appears with a row for each day of the week.

For each day:

1. Toggle the day on or off using the switch on the left. Days with the switch off are treated as closed all day.
2. Set your open time and close time using the time fields (HH:MM format, 24-hour clock — for example, 09:00 for 9 AM and 17:00 for 5 PM).

At least one day must be enabled. The open time must be earlier than the close time on the same day.

After Hours behavior

When a caller reaches your receptionist outside your scheduled hours, choose what happens:

• Take a message — your receptionist lets the caller know you are closed, collects their name, reason for calling, and a callback number, and sends you a notification. Callers are not left hanging.
• Play closed message — your receptionist tells the caller your office is closed and ends the call. No message is collected.

Saving

Click Save Business Hours to apply your changes. Changes take effect on the next incoming call — there is no need to restart anything.

Call Screening tab

Spam Filter

The Spam Filter toggle enables an automated robocall screen. When it is on:

• Callers who fail STIR/SHAKEN verification (a phone network standard that flags unverified caller IDs) are prompted to press a key to continue.
• Robocalls, which cannot press a key, are hung up automatically.
• Real callers press the key and are connected to your receptionist with no noticeable delay.

Turn this on if you are receiving robocalls or telemarketer calls on your business line.

Blocked Numbers

The Blocked Numbers section is a list of phone numbers that are permanently rejected — they never reach your receptionist at all.

To block a number:

1. Enter the phone number in the input field. Use E.164 format: a + sign followed by the country code and full number, with no spaces or dashes. For US numbers that looks like +12125551234.
2. Optionally enter a Reason (for your own records — callers do not see this).
3. Click Add (or the equivalent button next to the input).

The number appears in the table with the reason and the date it was blocked.

To unblock a number: Click the delete button on the right side of the row. The number is removed immediately.

Tips

You do not need to change your public phone number. Call forwarding sends calls from your existing number to Azumo. Customers keep calling the number they already know. Only you see the Azumo number.

Test forwarding with a call from a friend. After enabling forwarding, have someone call your business number and confirm your AI receptionist answers. Carrier forwarding codes can take a minute to activate.

“Take a message” after hours is almost always the right choice. Callers who reach a “we are closed” message and get hung up on often do not call back. Collecting their information means you can follow up the next business day.

Block numbers sparingly. The Spam Filter handles most robocalls automatically. Use the blocked numbers list for specific numbers you know are problems — for example, a persistent telemarketer or a caller who is harassing your staff.

Business hours only control when the receptionist answers — not when notifications go out. If a message is taken at 2 AM, the notification (Slack, email, or SMS) goes out immediately regardless of hours. Configure your notification preferences under Settings > Notifications if you only want to be alerted during business hours.

Troubleshooting

The Phone tab shows “No phone assigned yet.” Your number has not been provisioned. Contact support@azumo.com — phone provisioning is handled by your Azumo administrator, not something you can do yourself from the settings page.

I set up call forwarding but callers still hear my old voicemail. Carrier forwarding can take a few minutes to activate. Wait two or three minutes and try a test call. If it still goes to voicemail, double-check the forwarding code — an extra digit or a missing * will cause it to fail silently. Also confirm you dialed from the phone line you are forwarding (not a different phone on the same account).

I want to forward a landline, not a cell phone. The forwarding codes for AT&T, Verizon, and T-Mobile shown in the app are for mobile lines. If your business uses a landline or a VoIP provider not listed, contact your phone provider directly and ask them to set up “unconditional call forwarding” to your Azumo number.

My “Set a Schedule” shows an error when I save. Two things cause validation errors: (1) the open time is the same as or later than the close time on the same day — fix the times so the open is before the close, or (2) every day is toggled off — enable at least one day.

Legitimate callers are being asked to press a key. STIR/SHAKEN verification is not perfect — a small number of real callers on certain older carrier networks may fail verification. If you are seeing frequent false positives, turn the Spam Filter off. You can still use the Blocked Numbers list to handle specific problem numbers manually.

A blocked number is still getting through. Confirm the number was entered in E.164 format with the + prefix (example: +12125551234). If the number shows differently in caller ID (for example, with a different country code or formatting), add that version of the number as a separate block entry.
