When a customer dials PSTN number, they receive following response from Sipwise - Call Failed: 403 Forbidden. However when the same customer dials a number that is already registered to some other customer on Sipwise (different domain within Sipwise) the call goes through. I’m not sure what I’m forgetting or how do I troubleshoot this problem.
