Hello There! I’m Md Toriqul Islam, an experienced VoIP and automation developer with 10+ years of expertise in SIP, PBX, APIs, and AI integrations. I have a few questions: 1. Which carrier and VAPI BYOC configuration are currently available? 2. Is your Yeastar P550 publicly reachable or connected through VPN? 3. Should Google Sheet dialing run continuously or on a scheduled batch? I understand you need VAPI connected to your carrier and Yeastar P550 for automated outbound calls, with Google Sheets driving numbers and verified call records. My skills in SIP trunks, Yeastar, VAPI, PBX routing, Google Sheets APIs, and call automation fit this project. I can start immediately and validate the complete call flow end-to-end. Looking forward to hearing from you. Best regards, Md Toriqul Islam

Hi, I see you're looking to integrate the VAPI Voice AI with your Yeastar P550 PBX to enable seamless outbound calling. I have extensive experience with PHP and SIP trunk configurations, which are crucial for this task. By configuring your carrier’s SIP trunk inside VAPI, I can ensure that all calls will efficiently route through your existing minutes and numbers, leveraging your local carrier as a BYOC trunk. This setup will allow the AI to place calls using phone numbers stored in your Google Sheet, streamlining your communication process. Could you share more about any specific challenges you've faced with the current setup, so I can tailor the integration accordingly?

@thomasb726

Hello, SIP header mapping and RTP pathing are the most likely failure points: VAPI must present the carrier caller ID and P-Asserted-Identity in a way Yeastar accepts, and RTP/ICE/NAT traversal needs explicit handling so audio flows between VAPI, your carrier, and the P550 without one-way audio or registration churn. I have deployed multiple on-prem PBX integrations with cloud dialers and custom SIP trunks, including projects where I routed customer minutes through a BYOC trunk and normalized caller ID headers so the PBX treated AI-originated calls as normal trunk calls. I have hands-on experience with Yeastar-style SIP settings, translating From/To headers, setting P-Asserted-Identity, and verifying CDRs on the PBX side. I also built scripts that poll Google Sheets and feed numbers to outbound dialers with scheduled batching and real-time triggers. I will begin by validating carrier SIP credentials inside VAPI and creating a BYOC trunk with explicit SIP header rules, codec negotiation, and NAT/RTP policies. Next I will map trunk caller IDs and extension routing on the Yeastar P550 and wire a lightweight script to read the Google Sheet and push dials into VAPI for testing. - Do you prefer real-time polling or scheduled batches for the Google Sheet dial list? - Can you provide carrier SIP credentials and a test number so I can start lab verification? Happy to connect for a short call to walk through the approach. Thomas Beigbeder

Hi, I looked at your requirements and the key challenge is bridging VAPI, the on-premise Yeastar P550, and your carrier so outbound AI calls behave reliably like normal PBX traffic. I’d establish the SIP/BYOC routing first, map caller IDs and PBX handling, then connect the Google Sheet dialing flow and verify calls and CDRs on both sides. Quick questions: Q1. Is the carrier currently terminating directly on the Yeastar P550, or will VAPI connect to the carrier independently? Q2. Should the Google Sheet dialer start calls sequentially, or can multiple calls run concurrently? These clarify the SIP routing and dialing architecture before configuration. I’ll focus on a working end-to-end call flow that’s ready for the later routing milestones. Jonas Dedzo*

In addition, I have solidified my network administration (Routing, Switching, VPNs) expertise by working with numerous industry-leading vendors such as VMware and Cisco. Another testament to my effective service delivery is excellent client relations-I prioritize open communication and quick response to ensure that your needs are addressed promptly throughout the course of the project. My availability rounds the clock will also facilitate timely feedback on all matters ensuring efficiency at each step. Partnering with me means getting competent hands on deck who not only understand the capabilities and potential challenges of integrating technologies but also stay updated with the current best practices so that you receive a solution that deftly combines innovation with reliability. I look forward to a strong collaboration and delivering full satisfaction for your required Voice AI - PBX integration project!

@KasjanovaEste

Hi, I looked at your requirements and the key is making VAPI, the Yeastar P550 and your carrier behave as one reliable outbound calling flow, with the Google Sheet driving the call list. I’d first validate the SIP/BYOC routing and caller ID handling, then connect VAPI to Yeastar and implement the Sheet-driven dial workflow. I’ll test mobile and landline calls, verify call records on both sides, and document the configuration for repeatable use. Quick questions: Q1. Is the carrier SIP trunk currently registered directly on the Yeastar P550? Q2. Should the Google Sheet trigger calls automatically on a schedule, or only when an operator starts a campaign? These clarify the SIP routing and dialing workflow before configuration. I can take ownership from SIP setup through test calls and handover. Fernando

@ankits0192

Hi, hope you’re doing well! Your VAPI-Yeastar setup depends on getting the SIP path, caller ID and routing correct end-to-end, so the key is making the AI calls behave like normal outbound PBX calls while keeping the call records consistent. I’d configure the carrier as the BYOC route, connect VAPI with the Yeastar P550, verify extension/caller-ID routing, then connect the Google Sheet to the dialing flow and test both mobile and local numbers. I’d also verify CDRs on both sides after each test. Will the Google Sheet contain only numbers, or also fields such as campaign name and call status?

@naveed254

This is a BYOC trunk configuration job, and the P550 side is where most of the work sits. Approach: register your carrier as a BYOC trunk in VAPI with correct SIP credentials and codec negotiation (G.711 unless there's a reason otherwise - transcoding adds latency the agent will feel). On the Yeastar, a SIP trunk to VAPI with matching inbound and outbound routes, then a route that hands the specific DIDs to the agent while everything else stays on the existing plan. Then the parts that get skipped: NAT and SIP ALG handling on the firewall, RTP port ranges opened correctly, and DTMF passthrough if the agent needs to transfer. I run VAPI agents in production and have 17 years on PBX and network infrastructure. Is the P550 on a public IP or behind NAT, and is the carrier trunk already live on it?
