First of all, your provider should never route based on the To header but based
on the request uri. 

The contact is not used for the CLI, that's the from header. The contact can
contain random strings and it's also recommended that way. I don't get why the
contact should contain the telephone number. 

So instead of using the ruri and the from, they want to use the To and Contact
headers for their routing decisions? That makes no sense to me.
