Technically, there are a few ways to modify your outgoing caller ID without a dedicated spoofing app, but each has significant limitations compared to a proper SIP setup.
Some carriers let you hide your caller ID in settings (Show My Caller ID: Off). This shows "Private" or "Unknown" to recipients. It doesn't let you display a different number — it just hides yours.
Dialing *67 before a US number blocks your caller ID for that call. Again, this hides your number rather than changing it. Many people don't answer calls from "Private" numbers.
SpoofGlobal's IP2IP mode doesn't require a softphone app. If you have a static IP address, whitelist it in the bot, and send SIP traffic directly from any device on that IP. This works with:
With IP2IP, there's no registration, no app, and no softphone. Just route your outbound SIP traffic to SpoofGlobal's server from your whitelisted IP.
For most people, installing Zoiper (free, takes 30 seconds) is the simplest path. It's not really an "app" in the sense of bloated spoofing apps with subscriptions — it's a lightweight SIP client that just connects to the server. The actual spoofing happens server-side.
Only with IP2IP mode if you have hardware SIP phones or a PBX. For most users, installing a free SIP client like Zoiper is the easiest approach.
No. *67 only hides your number, showing Private or Blocked to the recipient. It does not let you display a different number.
IP2IP means your IP address is whitelisted on the server. Any SIP traffic from that IP is accepted without username/password registration. No app needed — just SIP-capable hardware.
