Capabilities

The Toshiba IP Telephones also have the following capabilities:
• The IP telephones contain two types of codecs (coder/decoder): G.711 and G.729A. The codec
determines the IP telephone voice quality and network bandwidth requirements. The G.711
requires the most bandwidth and provides the best voice quality. The G.729A requires less
bandwidth, but it does not provide the best voice quality. The desired codec can be selected for
each IP telephone in IP station administration using Enterprise Manager.
• The external ringer interface connector is mounted inside the telephone base. This enables
connection of an BESCB external speaker device to provide a loud ringer for the IP telephone.
• All telephones in the system can be IP telephones up to the system's maximum station capacity
(see
• Terminal Authentication is an option that allows a particular IP telephone to keep a reserved
directory number on a IPedge system. This prevents IP telephones from logging in with another
telephone's directory number if the other telephone has been disconnected to be taken to
another location. This feature uses the unique Media Access Control (MAC) address that is
permanently coded into each telephone network interface circuit. The unique MAC address of
the telephone is assigned to a particular directory number in system programming.
• IP telephone firmware can be updated locally or remotely using Enterprise Manager. This
enables service personnel to update IP equipment with new features and enhancements as they
become available. Updates require a brief interruption of IP telephone operation (a few
minutes).
• IP telephones have a discovery retry timer to prevent network congestion when many IP
telephones request services simultaneously. If network congestion is detected, the telephone
will pause and then retry for service.
• IP telephones have loop back and ping capabilities for maintenance and fault finding purposes.
• IP telephones support Dynamic Host Configuration Protocol (DHCP) or static IP addressing.
