I inputed my SIP credential in External Provide Keys. And I integrated it in BYO SIP Trunk Number But it gets "reject" if I make a call to DID number

Yes, Vapi can reject your custom SIP connection if the SIP credentials in External Provider Keys are missing, incorrect, or if your SIP client fails to respond to authentication challenges. Double-check that your credentials (username and password) are correct and that your SIP provider responds properly to the 401 challenge. For example, your payload for creating a SIP trunk credential should look like:

json
{
  "provider": "byo-sip-trunk",
  "name": "My SIP Trunk",
  "gateways": [{ "ip": "your.sip.provider.ip", "port": 5060 }],
  "outboundAuthenticationPlan": {
    "authUsername": "your_outbound_username",
    "authPassword": "your_outbound_password"
  }
}

Make sure your configuration matches your provider's requirements and test the connection again.

We inputted SIP credential in "External Provide Keys". Then, we created

phone number

in "Phone numbers" -> "Created Phone number" -> "BYO SIP Trunk Number" We inputted this. https://cdn.discordapp.com/attachments/1372352679745028126/1372428391650820136/0.png?ex=6826bd0b&is=68256b8b&hm=3846c6bceb4e3267e4f6051dde85bf8e0a6f65db9226fefe805490a86eab8305&

Hey, Could you please schedule a brief call at your convenience so we can discuss this matter in detail? Kindly use the following link to book a suitable time: .

@Shubham Bajaj The problem above is exhibited by improper INVITE dialog initation, from the VAPI side as I see it. Pay attention to the first rejection from the remote side, which contains the realm as:

sip.vapi.ai

- which is really odd, as it should have been

hvjmg6s.se.vsrns.com

- this potentially means that VAPI sends the outbound invite with a username that isn't formatted correctly. Also, the last error says clearly:

"X-Reason: Invalid credentials"

, which means that the combination of

realm

and the

authorization

challenge don't correlate to their database scheme - which makes sesne, as

sip.vapi.ai

isn't part of their SIP Domains.

So, what should I do next ? @Nir S (CEO/Founder @Cloudonix)
