• TCP protocol
The main task of this protocol is to transfer data securely through the network.
• UDP protocol
Unlike TCP, this protocol does not confirm transfer or implement other security
measures. This means that UDP is, however, more efficient and therefore
suitable for high-speed applications.
IP Telephone ↔ IP Office
The ISDN configuration information is packed into a data packet (payload/user
data). It is noted in the
IP
header that the
TCP
protocol is to be used. The data
packet is now
securely
sent to the recipient.
Security
is of the essence when
configuration information is being transmitted.
The voice information is also packaged into a data packet. It is noted in the
IP
header that the
UDP
protocol is to be used. The data packet is now sent to the
recipient
quickly and unsecured
.
Speed
is of the essence when voice
information that must arrive in good quality is being transmitted.
AND
All IP Office-specific codings of a system telephone remain intact.
