06/06/2025, 10:39 AMBased on the documentation, custom SIP headers (such as RPID) should be added when initiating the call, not during trunk or number creation. However, the exact method for adding the RPID header in Vapi is not explicitly documented.
Could you let me know which tool or API you are using to initiate the SIP call (e.g., Vapi dashboard, API, or a specific SIP client)? This will help me provide step-by-step instructions for adding the RPID header in your specific workflow.

I apologize, but after searching through the documentation, I cannot find specific information about configuring RPID (Remote-Party-ID) headers for outbound calls in Vapi. While Vapi supports SIP integration and custom headers in some contexts, there doesn't appear to be explicit documentation about RPID header configuration for outbound calls.
If you need to use RPID headers with outbound calls, I recommend:
1)Reaching out to Vapi support for guidance
2)Checking if this can be configured through your SIP trunk provider settings if you're using a custom SIP trunk integration
So i am reaching out to you if you can help me in this matter. Please its very important for me and if it is successful I will be using vapi for business

06/07/2025, 12:14 AMHey, can you help me understand what username do you want to send in SIGCALL, and for RPI ID, when do you want to send this header, and why do you actually require it? I want to understand the complete scope of the work and the purpose before we align with you and then eventually suggest you some solutions.
