Hi Retell team 👋 I’m using Retell with Telnyx (SIP Trunk, inbound calls). Problem: The caller phone number is visible in Call Logs (Phone Call: 07xxxxxxxx -> +4xxxxx), but it is NOT available inside extract_dynamic_variables. Example result: "customer_phone": "Not provided" or sometimes "caller ID" I want to include the caller’s phone number in: - SMS summary - webhook / post-call summary Question: What is the correct variable / config to access the inbound caller number? Session id : call_bc1cee1d3f96a8273e76793bb2e
