Why it matters
SIP users connect people or devices to SIP voice infrastructure. Keeping them accurate supports calling, extensions, and device provisioning.
Key Concepts
SIP user: A SIP identity used for authentication with a provider account.
Domains: The SIP Users table shows the domains associated with each user where available.
Password: SIP user password fields can be shown, hidden, or copied where the UI provides those controls.
Step-by-Step: Review SIP users
Open Settings > Accounts.
Open the provider account you want to manage.
Select the Users tab.
Review existing SIP users and their associated domains.
Create or update a SIP user when a person, device, or extension needs SIP authentication.
Copy domain or password details only when needed for setup.
Test the dependent device, extension, or phone after changing a SIP user.
Tips and Best Practices
Create SIP domains and credential lists before setting up SIP users.
Treat SIP passwords as sensitive credentials.
Use clear usernames so devices and extensions can be traced later.
Remove unused SIP users as part of access cleanup.
Troubleshooting
Issue | Possible Cause | Fix |
SIP user cannot authenticate | The password, domain, or credential list relationship may be incorrect. | Review the SIP user, domain, credential list, and attachment setup. |
Domain copy is needed | A device or softphone setup may require the SIP domain. | Use the domain copy control in the SIP Users table where available. |
Cannot create a SIP user | Required SIP infrastructure may not exist yet or your role lacks permission. | Confirm the provider account has the required domain and credential list, then ask an admin if access is blocked. |
