Please note that the base number CLI logic can be broken by NAT. We initially look for a registration for the number we have on a call (e.g. DDI), and if found, we use it. If not, and if base number is set, we check if the base number has a registration. If so, we use the DDI followed by the contact from the registration. When NAT is used we can't trust the contact for the registration. |
