How to configure Freezvon SIP on your smartphone

Nikker

Hey everyone,
I just bought a virtual number from Freezvon and I’m trying to set it up on my Android phone using Zoiper. I’ve got the login details (SIP login, password, SIP domain), but I’m a bit confused with the rest of the settings. Has anyone here successfully configured Freezvon SIP on mobile?

Hey! I’ve set up Freezvon SIP on my Android using Zoiper, and it works great once you get the settings right. After entering your SIP login, password, and the SIP domain (usually sip.freezvon.com), make sure to leave the rest of the settings as default. You might also need to enable STUN if registration fails. Freezvon is a good option for online communication and cloud telephony  — reliable call quality and fast SMS delivery. If you're still stuck, their support team is super helpful and quick to respond. Let me know if you need screenshots!
