I’ve worked with several Vapi–Telnyx setups and can help fix the 12-second delay by checking how your SIP and agent session initialize. It’s usually a timing or media handshake issue that can be fixed with a few config tweaks. I’d like to review your session logs to confirm where it’s happening. Does the delay occur on both inbound and outbound calls? I’ve also built AI voice agents for real estate teams, so I know how important quick response time is. @TeoTheBeast
