iPhone Setup - SynergyCloud VettedCalls

About 10 minutes start-to-finish. Keep this page open on your computer while you follow along on your phone.

Step 1 of 5

Install the SynergyCloud VettedCalls phone app

Tap the App Store install link in your VettedCalls welcome email (it points to the 3CX phone app, which is the SynergyCloud VettedCalls client). Or open the App Store and search for 3CX as a backup. Direct link. Free.

Why this matters: Screened calls reach you via VoIP push notifications instead of your cell line - no carrier dependency, no silent-ring delay, and you can answer from any iPhone you log into.
Step 2 of 5

Open your VettedCalls welcome email and tap the activation file

Find the SynergyCloud VettedCalls welcome email in your inbox on your iPhone. Tap the attached file (vettedcalls-XXXX.3cxconfig). iOS shows a share sheet - scroll and choose Copy to 3CX. The app opens and provisions your VettedCalls extension automatically.

Why this matters: The activation file holds your VettedCalls credentials. Tapping it sets up the phone app in seconds - no usernames or passwords to type.
Step 3 of 5

Allow the requested permissions

When the app asks, tap Allow for every prompt: Microphone, Notifications, Contacts, and Local Network. Then go to iPhone Settings → 3CX → enable Background App Refresh.

Why this matters: iOS will not wake an app to receive a call without Notifications and Background App Refresh enabled. Without these, the app cannot ring you when a screened call is bridged through.
Step 4 of 5

Forward all calls to your VettedCalls extension

Open your iPhone's regular green Phone app and dial the forwarding code for your carrier (pick yours below). Press the green call button. Wait for the short confirmation tone.

Forward all calls to VettedCalls**21*NUMBER#
Disable forwarding later##21#

Replace NUMBER with the digits of your VettedCalls extension number (from your activation email, no spaces or punctuation). Wait for the short confirmation tone after dialing.

Why this matters: This is the standard unconditional call forwarding code your carrier supports. Every incoming call now routes to VettedCalls first; spam is screened, legitimate calls are bridged through to your VettedCalls extension.
Step 5 of 5

Test it - have a non-contact call your cell

Have someone (a friend, family, or a phone not in your contacts) call your regular cell number. Your iPhone should not ring. After about 3-5 seconds, the 3CX app should ring with the screened call. Answer it like any normal call.

Why this matters: If your iPhone rang, the forwarding code didn't take - try dialing it again. If 3CX didn't ring, check Settings → 3CX → Notifications is ON, and Background App Refresh is enabled.

You're live.

Unknown calls now route to VettedCalls. Your contacts ring through directly. Emergency-keyword callers (flood, gas, no heat, sparking, burst, leak) always reach you.

If anything feels off in the next 24 hours, text HELP to your VettedCalls number and we'll walk it through with you.
