“Dialing” in ReadiVoice-IP Systems

For the sake of simplicity, we refer to “dialed phone numbers” throughout this

document. Actually, in IP telephony, end points are identified by a Universal
Resource Identifier (URI).
This URI resembles an email address: phonecontact@domain. Domain is
pretty much what one would expect: something.com or something.org, for
example. Phonecontact can be anything that identifies a device known to the
domain, such as a name, a 10-digit phone number, or perhaps an extension
number.
The ReadiVoice-IP system uses the Session Initiation Protocol (SIP) to
communicate with other IP telephony equipment. It sends out formal SIP

URIs, but users can “dial” any of the following:

Formal SIP URI

The URI described above preceded by the name of the protocol and a
colon. For instance:
SIP:3032235000@voyanttech.com
SIP:brent@voyanttech.com
SIP:5000@voyanttech.com

Simplified URI

The URI with the protocol name omitted (similar to omitting the “http:” in
a Web address). For instance:
3032235000@voyanttech.com
brent@voyanttech.com
5000@voyanttech.com

URI Without Domain

If your system is configured with a default domain and port, it routes

addresses that don’t specify a domain to the default domain and port. For
instance:
3032235000
brent
5000

Since most of the world is still using the PSTN and ordinary phone numbers,
your ReadiVoice-IP system undoubtedly sits behind one or more gateways to

the circuit-switched network. When your system is given an ordinary phone
number with no domain specified (such as the example 3032235000 above), it
routes the call to the gateway (or to a router that sends it to the appropriate

gateway).
