Configure or recover your SIP extension
Product guides, public API, webhooks and MCP.
Open your number and select Ramal / App / Softphone in forwarding options. Save and use the displayed username, password and server in your calling app.
If creation fails, the password is missing or an existing-extension error appears, open Suporte > Novo chamado with the number and approximate time. You do not need to buy another number to fix configuration. Never send the SIP password in a ticket.
After support corrects the issue, reload and check current credentials. Update the app if the password changed, check registration and make a test call on your own network. A technical configuration check does not replace that test.
Ending a number service disables its exclusive extension and credentials. A later purchase never grants the previous owner's credentials. Shared resources may require support review.
