Strange now it's working with the called number being passed in the "To" field. I must have just not seen it before. However, it's not really passing the called number per say. What it's doing is putting the extension I have in my register statement into the "To" field. I'm assuming the "To" field is actually being populated with whatever * set the "Contact" field to when it registered. This seems to mean that I need a unique username for every SIP DID I have if I want to be able to route them to different context's. Is there a standard way of handling this issue when you have multiple SIP DID's ?
