You can dial out to a list of phone numbers, endpoints, or a combination of numbers and endpoints at the same time using simultaneous dialing.
The following example shows how to simultaneously call a list containing two endpoints and one phone number. This will dial out to all the numbers and endpoints mentioned in the XML element. The first of these calls to answer is connected to the current caller, while the rest of the connection attempts are canceled. You can combine endpoints and phone numbers in one XML element.

The same result can be achieved through PHLO by using call forwarding with parallel dialing.
