Hey Vapi team 👋 I have a confirmed root cause for my outbound call failures and need urgent help. Telnyx support just confirmed the issue is on Vapi's side: The exact error: > "Dialed number +34663586605 (associated countries: ESP) is not included in whitelisted countries USA, CAN, COL, BRA, PAN, MEX, SLV, SGP" Telnyx confirmed this whitelist does NOT come from their platform — it's being generated by Vapi. Spain (ESP) is missing from Vapi's internal country whitelist for my BYO SIP Trunk integration. My details: - Phone Number ID:

70440630-df91-4d30-9d43-bd23dc2f160b

- Credential ID:

a4da714a-c335-490c-8763-9793f2f42598

- Number:

+34967920306

(Spain 🇪🇸) - Error:

call.in-progress.error-sip-outbound-call-failed-to-connect

- Call IDs:

019d85b4-336f-7ee5-b60f-dedf990ee88f

,

019d86b2-6ac6-7000-9b9e-57a01c4a02b7

What I need: Spain (ESP / +34) added to the country whitelist for my BYO SIP Trunk. This is blocking production. Can someone from the team take a look? 🙏

Thanks for the detailed breakdown this is very clear. This definitely looks like a country whitelist limitation on Vapi’s side rather than Telnyx. I can help you escalate this properly or even help you implement a workaround (like routing via an allowed region or adjusting the SIP config) while the whitelist is updated. @marcos

Please help me make the solution while they look at it, but if you can escalate it, you would do me a favor

I’ll handle the workaround setup and also escalate this for you. To proceed quickly on my side, I’ll need access to your current Vapi + SIP/Telnyx configuration (or the relevant credentials/settings). Once I have that, I can implement the temporary routing fix while we wait on the whitelist update. I’ll keep you posted as I make progress. @marcos

Hi, I'd prefer not to share API keys directly for security reasons. Here's all the config info you should need: Org ID: 6b5b2dc8-43fe-414d-afb9-deead6e256ab Phone Number ID: eb52ccf5-648d-4c8d-8065-683aa44b6356 Provider: Telnyx / Number: +34967920306 Error call ID: 019d8c27-60e5-7ffd-8ae3-6c6819e4f9b2 Error: sipStatus 403 - ESP not in whitelisted countries If you need direct account access, let me know what specifically you need and we'll arrange it securely.

Perfect, this is enough to move forward thank you for sharing it. I’ll start by checking the SIP routing and Vapi/Telnyx configuration using these IDs and replicate the 403 whitelist issue so I can implement a proper workaround. Just a quick note this kind of deep configuration fix and temporary routing setup comes with a fee since it involves direct troubleshooting and implementation. If you’re interested, we can take this forward via DM and I’ll outline the approach clearly for you. I’ll also escalate the whitelist issue using the error call ID you provided and keep you updated as I progress. @marcos

You are not support oficial of Vapi

You’re absolutely right I’m not Vapi official support. I’m working with you as an independent freelancer to help diagnose and implement a workaround around the current limitation. What I can do is help you troubleshoot the configuration, replicate the issue, and set up a working routing solution while Vapi handles the whitelist from their side. Let me know if you’d like me to proceed and we can take it from there. @marcos

I dont going to give u money

hey @marcos we see the error on our SIP server and we reported it to the team. in the meantime, if you would like to try another SIP provider, we have a recommendation for you. ill send you a DM with the details
