C Glossary
Cellular data call A Bria call that uses the cellular data newtork rather than the Wi-Fi network. If you
start (or receive) a call with an iPad when you are not in a Wi-Fi zone, the call will be
a cellular network call. Not all supported devices support 3G; see page 3.
Codec Codecs are programs in Bria involved in transmitting audio; each codec has different
characteristics and therefore each works better in some situations than in others.
DTMF Dual-tone multi frequency. DTMF is the system that is used in interactive voice-
response menu systems such as the menu system for accessing voicemail messages.
The DTMF system allows the user to interact with the menu by pressing keys on a
dialpad or keyboard.
Home button The button at the bottom of the iPad.
IM Instant Messaging. A technology that lets users send text messages for near
instantaneous delivery and display on each others’ devices.
ICE Interactive Connectivity Establishment. A method for traversing a firewall.
IP address A unique number that identifies a device. Devices on a network use the IP address to
communicate with each other.
IVR Interactive Voice Response. IVRs use DTMF.
Media The audio portion of a call. Compare to “ Signaling”.
PSTN Public Switch Telephone Network. The traditional land-line phone network.
Presence An instant messaging feature that allows users to share information about their online
status.
Signaling The information in a call that deals with establishing and controlling the connection,
and managing the network. The non-signaling portion of the call is the Media.
SIP Session Initiation Protocol. The signaling protocol followed by Bria for handling
phone calls.
SIP account An account that provides the user the ability to make VoIP phone calls. The account
encapsulates the rules and functions the user can access.
softphone address The address used to connect to a SIP endpoint. In other words, the “phone number”
used in a VoIP phone call. For example, sip:[email protected].
STUN Simple Traversal of UDP through a firewall or NAT.
Wi-Fi call A Bria call made over the Wi-Fi internet. To make a Wi-Fi call, you must be in a Wi-
Fi zone.
XMPP account An account that provides the user with the ability to send IMs and view other people’s
presence.
3G call A Bria call made over the cellular network. Same as a cellular data call.
