    I made a fake trunk for,

    Then, created a new outbound route dial:0 strip:1 prefix: Extension number

    It is working for me and is used in our office. 

    I made the same config for a customer today, but it did not work. I also tried to create a new ring group numbered "0", but it did not work again. 

    I'm so confused about why it worked in the same version as a PBX and why others do not.
