Question

I am working on Twilio APIs and trying to send fax using Programmable fax but i am getting this error.

[HTTP 403] Unable to create record: Dialing to this country is not permitted by your account's international permissionsRequest done

Below is my code to send fax.

    $sid = config('services.twilio.sid');
    $token = config('services.twilio.token');

    $client = new Client($sid, $token);
    try {
        $fax = $client->fax->v1->faxes->create(
            "+92304xxxxxxx", // to
            "https://www.twilio.com/docs/documents/25/justthefaxmaam.pdf", // mediaUrl
            array("from" => config('services.twilio.phone_number') )
        );
    } 

Anybody please help?

Thank you.

Have you ensured that the country you are trying to send the fax to is selected on your geographic permissions for voice calls ? Fax is sent over the voice channel not the messaging channel, so even if you can send SMS messages to the country, you may not have given permission for voice/fax yet.
