IP phone’s network address. The address that you use instead is easier to understand,
i.e. the phone’s e-address or public address.
These addresses are designed like email addresses, i.e. name@domain, for example
bob@company.com. A complete URI (Uniform Resource Identier) is created when the
protocol that is used to communicate with the resource is added to the address. A URI
might look like this: sip:bob@company.com.
URIs can be used instead of phone numbers to make calls from one IP phone to
another.
