Request Timeout When Registering


I am a newbie about general SIP and PBX so please bear with me. I tried searching before asking this question but couldn’t solve my problem even if I found several answers.

My question is I’m trying to setup FreePBX on a DigitalOcean droplet. I successfully installed and can login to admin GUI. Problem is I don’t know how to login using an android client like Zoiper or CsipSimple. What should be the username, password and hostname? I tried host with droplet public ip address:5060 but android application still somehow gives timeout error. I hope someone can help me about this issue.


Username is your extension, password is your extension’s password. Hostname in Zoiper is as you say. PublicIP:Port (In others like CSip the port is entered separately). Now the port is normally 5060 if you setup your extension using PJSIP, or 5160 (sometimes 5061) if you set it up using Chansip. Freepbx usually says “This device uses PJSIP technology listening on Port 5060 (UDP)” in the general tab of a particular extension. Except - If you are using IAX it doesnt though but you can goto the Extension and click on the “Advanced” tab and look for “port”. Normally 4569 if you used IAX.

You may also want to check your firewall. Start with wifi where hopefully your phone’s IP address is the same as the computer you are using to log onto Freepbx is one way to rule that out.


Thanks for your reply. I had already suspected it was a firewall issue as you said and tried disabling firewall but still no luck. I hope these outputs will be useful:
