Hi greal1914, The error code

call.start.error-get-transport

indicates an issue retrieving transport information during the start of a call. This might involve misconfigured or missing transport details when setting up your call using the Vapi platform. To address this, ensure you have configured the

transport

property correctly in your call configuration as an object, as per the [April 8, 2025 update](https://docs.vapi.ai/changelog/2025/4/8). This update replaced the deprecated separate

Transport

schema with a simplified configuration directly within the

Call

object. If you've already made this change and are still encountering the error, double-check the transport type (such as

sip

,

pstn

, or

vapi.websocketCall

) is correctly set and that any required provider details are complete and accurate.
