@Felipe Hidalgo It seems like you might be referring to Asterisk, which is an open-source framework for building communications applications. If you have any specific questions or need assistance with something related to Asterisk or voice applications, please let me know how I can help you!

@Felipe Hidalgo Your SIP Provider Asterisk doesn’t sends a username/password entry for the sip.vapi.ai. When the Vapi sends a 401 challenge, Asterisk can’t respond with valid credentials, so the call fails.

I am the provider. Where I need to put the user and password in vapi. the numberI created do not have any credential (user/pass) . In what sip field or header should arrive the user and password.

@Felipe Hidalgo Vapi expects authentication credentials. The username must be your SIP username, and the password can be anything except the keyword "test." Authentication is handled using the Authorization header in SIP. When you send an initial

INVITE

, it does not include credentials. The Vapi server responds with

401 Unauthorized

, along with a

WWW-Authenticate

header containing a nonce value. This nonce is required for digest authentication. To authenticate, you must resend the

INVITE

with an

Authorization

header that includes: - **username**: Your SIP username. - **realm**: The domain provided by the server (

sip.vapi.ai

). - **nonce**: The nonce value from the

401 Unauthorized

response. - **uri**: The request URI (e.g.,

sip:1111212@sip.vapi.ai

). - **response**: A computed MD5 hash using the following formula: Without this

Authorization

header in the second

INVITE

, the server will reject the request.

Thanks, issue solved. I will upload the Asterisk configs for future helping any other user that need it. Again, tnaks very much.

@Felipe Hidalgo Could you please clarify the issue at hand? Additionally, would it be possible for us to schedule a time to discuss a document that would assist users in utilizing Asterisk and Vapi effectively?

@Felipe Hidalgo Could you please share the Asterisk config files? Thank you in advance

We are on standby awaiting a response from Felipe. We will also mark this ticket as resolved for now
