Sadly i cant call a Mailbox/Mobilbox.<br> I could call my Phone with the Vonage API, but i cant call a PrepaidCard(from Telekom) neither the Mailbox/Mobilbox from my Phone.</p> <p>I also wrote the Vonage support, but they could not help me either.</p> <p>I just want to call a VoiceAPI to call a Mailbox/Mobilbox for a telekom number.<br> I'am out of options ...
