My Credentials Are Correct but SIP Won’t Register
In some cases — depending on your ISP or country — a phone extension cannot be registered over SIP. If you are entering the correct credentials but SIP registration still fails, follow the steps below to switch your extension to the IAX protocol.
- Log in to eDialer and navigate to your Phone Extensions.
- Click Modify next to the phone extension you need to change.
- Locate the Protocol field and change the value to IAX.
- Go to the Template ID field and select IAX Generic.
- Click Save Changes.
- On your softphone, delete the account you previously added.
- Return to the registration process and, this time, choose IAX as the protocol.
After completing these steps, your softphone should register successfully using the IAX protocol. If you continue to experience issues, please contact our support team.
