PortSIP is a free program for making calls over the Internet in any direction. The only thing required to ensure the quality operation of this service is a high-speed internet connection.

Following the instructions, you must create a SIP account in your Ringostat personal account before starting the program setup.

Setting up the PortSIP program:

  1. Download the application to your smartphone from the official App Store resource.

2. After installing the application, open it and allow the necessary permissions to your device.

3. If necessary, allow access to your contacts:

4. Allow sending notifications:

5. Enter your account details and SIP server, then press "Sign In":

SIP Login: SIP account login;

Password: SIP account password;

SIP Server: sip.ringostat.com.

If you received SIP account details from technical support, copy them from the correspondence or create a new password in your account:

6. Allow device discovery in your local network and connect to them:

7. The setup is complete, and the SIP account is ready to receive and make calls. Here is what the app window looks like when it’s ready for making calls:

Setting up the STUN server

If your conversation partner cannot hear you or vice versa, meaning there is a one-way audio issue, we recommend configuring the STUN server.

3. Press "Sign Out":

4. To enter our Ringostat STUN server, click "Advance":

Port: 3479

Then, proceed to data entry by pressing "Back":

Changing the data transmission protocol

We also recommend changing the data transmission protocol if you are experiencing one-way audio issues or cannot register your account for calls.

1. Click "Advance"

2. Choose the TCP protocol and press "Back" to save.
