SINCH PROBLEMS: 40303 User creation is disabled for this application

Hello Farouk Charkas,

just seeing now you requested help with this from me.

first, you do not state what course or module you are working on for this PSTN you say you're creating; also, most folk here won't know that a PSTN means public switched telephone network, or what used to be called POTS for Plain Old Telephone Service (what we now refer to as "land line" telephones). They also probably won't know that Sinch is a third-party cloud-based API for making phone calls or sms. it helps, if you want responses, if you explain these things a bit in your query.

i'm assuming you are coding this in JavaScript, as you asked for my help and that is one of my expertise? which treehouse course and module is this for? could you please post some code so we can see where it might be tripping up, that would be helpful.

also, in searching the Sinch API website, it says there a 40303 error is largely due to permissions — either the phone number you are attempting to dial has not been verified in your cloud Sinch account, or you're attempting to send an SMS to a phone number that also has not been verified in your cloud Sinch account.

let us know if this helps or if you have code or further info that would help track this down, particularly the treehouse course you are on and what programming language and/or API or Framework you're using.

best,
