in fact I do not know such a setting in my PBX, let me know how to configure?
Have you set a trunk sip line ?
you need almost one outbound rule to be able to call.
yes I am the administrator of the PBX I have all their informationHi @Ibrahima
If you are not aware of the outbound rules, are you the admin for the PBX?
If not then you need to speak with your PBX admin.
If this is a new installation, then let us know so we can tell you where to look to set it up properly
