Call forwarding is a feature provided by your mobile carrier, not by Beside. It redirects incoming calls from your main phone number to another number - in this case, your Beside line.
This means your contacts can keep calling the number they already know, while Beside handles the call in the background. Even if the Beside app isn't open, forwarded calls will still be picked up, enabling features like your AI Receptionist, transcripts, and call summaries.
When call forwarding is enabled, all incoming calls will ring on Beside - it's an all-or-nothing approach and cannot selectively manage calls based on individual contacts.
Set up call forwarding
Call forwarding is always managed by the carrier that owns your phone number (for example: Verizon, AT&T, T-Mobile). Setup methods vary depending on your provider.
⏱️ Heads up - carrier propagation delay: After you activate call forwarding with your carrier, it can take anywhere from a few minutes to a few hours for the change to fully propagate on the carrier's network and reach Beside. If your first test call doesn't work, wait a bit and try again before troubleshooting further.
On iPhone
The Beside app uses a guided, full-screen flow that works the same way for US and Canadian carriers:
Open the Beside mobile app
Go to Settings
In the Phone section, tap Call Forwarding
Business plan users: under Phone Numbers, tap the line you want to update first, then tap Call Forwarding in the Phone section.Confirm the existing phone number you want to forward to Beside
The app auto-detects your carrier and pre-selects it for you. Confirm it's correct, or select your carrier manually.
Tap Continue, then follow the on-screen prompt to place a call to activate call forwarding
After the activation call, Beside will verify that forwarding is working. This may take a few seconds.
📌 Tip: If verification takes longer than expected, the app will continue checking. If it can't confirm, it will guide you through a quick diagnostic to troubleshoot.
⚠️ Canadian carriers: You may see a warning about potential additional costs. Some Canadian carriers charge for call forwarding to certain area codes. The warning is informational - Beside does not charge extra. Any cost would come from your carrier
On Android
Carriers directly supported in the Beside app include Verizon, AT&T, T-Mobile, and Canadian carriers.
Open the Beside mobile app
Go to Settings
In the Phone section, tap Call forwarding
Select your provider
Follow the on-screen instructions
Once completed, contact your provider to confirm that call forwarding is active.
📌 Tip: If verification takes longer than expected, the app will continue checking. If it can't confirm, it will guide you through a quick diagnostic to troubleshoot.
If it doesn't work, use carrier dial codes
If the in-app setup fails or doesn't activate correctly on either iPhone or Android, you can enable call forwarding manually using your native phone dialer (not the Beside app).
📌 Example:
If your Beside phone number is
+1-234-567-8901And your carrier is Verizon: dial
*72followed by2345678901(area code + number, no +1)Final number to dial:
*722345678901
US carrier dial codes
US carrier dial codes

Verizon | *72BesideNumber (remove the +1) |
AT&T | *21*BesideNumber# (remove the +1) |
T-Mobile | **21*BesideNumber# (remove the +1) |
Visible, Xfinity Mobile, US Mobile, Spectrum, Boost Mobile | *72BesideNumber (10-digit number) |

For most Canadian carriers:
Open your phone's Phone app (native dialer)
Dial: *21* followed by your 10-digit Beside number and #

⚠️ Canadian area code cost warning: Some Canadian carriers charge for call forwarding to certain area codes. Beside does not charge extra for call forwarding setup. Any additional cost would come from your carrier.

Forward multiple phone numbers to Beside
You may want to forward more than one phone number to Beside - for example, if you have a personal number and a business number. Here's how each scenario works.
Scenario A - Multiple phone numbers forwarding to a single Beside line
Scenario A - Multiple phone numbers forwarding to a single Beside line
Several different phone numbers all forward their incoming calls to the same Beside line.
📌 Example: Your personal number (+1-555-000-0001) and your business number (+1-555-000-0002) both forward to your single Beside line (+1-234-567-8901). Every call rings inside the same line regardless of which number was dialled.
How to set it up:
On the phone or SIM for your first number, follow the standard setup steps above and enter your Beside number as the forwarding destination.
For your second number (and any additional numbers), use carrier dial codes from your native dialer - the in-app setup only works for the primary line.
⚠️ Important: When multiple numbers forward to a single Beside line, all calls arrive with no indication of which source number was used. If knowing the original number matters to you, use Scenario B instead.
Scenario B - Each phone number forwards to its own dedicated Beside line
Scenario B - Each phone number forwards to its own dedicated Beside line
Each phone number you own forwards to a separate Beside line, each with its own AI Receptionist, settings, and call history.
📌 Example: Your personal number (+1-555-000-0001) forwards to Beside line A, and your business number (+1-555-000-0002) forwards to Beside line B. Each line has its own AI Receptionist and call history
Requirements:
You need a 👥 Business plan to have multiple Beside lines.
To add a new line, go to Settings → Phone Numbers → Add a line.
✅ Recommended if you need to keep different numbers separate, use different AI Receptionist configurations per number, or track call history per source number.
Important notes
Call forwarding is fully controlled by your provider
Beside cannot enable, disable, or troubleshoot it on your behalf
Availability may depend on your plan, region, or provider rules
Some providers may not support forwarding to Beside at all
⚠️ Disable call forwarding before deleting Beside: If you're deleting the Beside app or canceling your subscription, make sure to disable call forwarding first. If it stays on, calls to your primary number may keep forwarding to Beside even if the app is no longer installed.
