How to Spoof a Phone Number on Android

SPOOFING CALLER ID ON ANDROID

Android doesn't let you change your outgoing caller ID through the default Phone app. To display a custom number on outgoing calls, you need a SIP client app connected to a caller ID spoofing service.

WHAT YOU NEED

• An Android phone (Android 8.0 or later recommended)
• Zoiper app (free on Google Play)
• A SpoofGlobal account with SIP credentials
• An active CLI route for caller ID display

STEP-BY-STEP SETUP

1. Get SpoofGlobal Credentials

Open @SpoofGlobalBot on Telegram. Create a SIP account and set your desired caller ID. Deposit balance and activate a route.

2. Install Zoiper

Download Zoiper from Google Play Store. Open it and skip the setup wizard.

3. Configure SIP Account

Go to Settings > Accounts > Add Account > Manual Configuration. Enter:

• Account name: SpoofGlobal
• Host: Your server IP
• Username: Your SIP username
• Password: Your SIP password
• Transport: UDP
• Port: 5060

Save and wait for "Registered" status.

4. Make Your First Call

Open the Zoiper dialer, enter a number in international format (like 12125551234 for a US number), and press call. The recipient sees your chosen caller ID.

ANDROID-SPECIFIC TIPS

• Battery optimization: Exempt Zoiper from battery optimization in Android settings so it doesn't get killed in the background
• Doze mode: On Android 6+, add Zoiper to the Doze whitelist for reliable background operation
• Default dialer: You can set Zoiper as your default dialer if you want all calls to go through SIP
• Codec priority: Set G.711 (PCMU/PCMA) as the priority codec for best compatibility
• Permissions: Grant microphone, phone, and notification permissions for full functionality
