“Turn your phone (or laptop) into a fully-featured SIP phone… and yes, it’s cooler than it sounds.”

Let’s get you calling with Bitcall and Zoiper — one of the most popular softphone apps on the planet.

🔸 Before You Begin

Make sure you’ve got:

  • ✅ A Bitcall account

  • ✅ Your Bitcall SIP account (it is created for you when you sign up)

  • ✅ Your SIP credentials (username, password, domain)

  • ✅ Internet (WiFi/4G/5G — no telepathy required… yet)

⚠️ If you’re using IP Authentication, skip the password part and make sure your IP is whitelisted in Bitcall.

  3. Enter your SIP credentials:

  1. Tap Next, then select SIP UDP

    (Or SIP TCP/TLS if you want encrypted calls)

🔄 Troubleshooting Tips

Issue

Fix

“Registration failed”

Double-check username, password, and domain

Can’t hear audio

Check device mic/speaker permissions and codecs

Still failing on mobile

Try switching transport (UDP → TCP) or use SIP IP: 188.34.143.144

Using IP Auth

Leave password blank, make sure your IP is added in Bitcall

Behind firewall/NAT?

Try enabling STUN in Zoiper settings

🧠 TL;DR Recap

✅ Use gateway.bitcall.io as your SIP domain 
✅ Register with your SIP username + password (or use IP Auth) 
✅ Choose UDP, TCP, or TLS transport 
✅ Use Zoiper on iOS, Android, Windows, or macOS 
✅ Registration = Success = Time to call!
