weekend calls

Calls from the vanbox via binotel do not work, you see the pardon "Binotel API pardon. Reverse integration." That is the problem with integration. I went all the way to Binotel's technical support, they stenched everything from their side and sang that the problem is in Vanbox itself, and not in them. Be amazed at the technical logs, like a pardon itself at the moment you try the last call and say, what could be the reason? How to fix it? Abo right your side. The installation of Zoiper has been successfully completed and the instructions are successfully received. The problem is only with the weekends.
