Internal Server Error Caused by Some Numbers in Calling SDK
SOLVE
While using the calling-extension SDK, some numbers cause a "500 internal server error" to occur on incoming calls when they are set in the 'toNumber' field.
This is different from a "400 bad request" error which occurs if the number itself is invalid. Also this only occurs on the 'toNumber', but not the 'fromNumber' field.
An example of the numbers I'm using that cause this are "+6909602" and "+690222".
My use case is that I'm using "+690" as a placeholder with 4-digit or shorter IP extension numbers, as a workaround to country code validation being enforced by HS.
