  (continued).  

Both TCP and UDP split data into 
packets called “datagrams.”  However, 
TCP includes extra headers in the 
datagram to enable retransmission of 
lost packets and reassembly of packets 
into their correct order if they arrive out 
of order.  UDP does not provide this.  
Lost UDP packets are unretrievable; 
that is, out-of-order UDP packets 
cannot be reconstituted in their proper 
order.. 
Despite these obvious disadvantages, 
UDP packets can be transmitted much 
faster than TCP packets --  as much as 
three times faster. In certain 
applications, like audio and video data 
transmission, the need for high speed 
outweighs the need for verified data 
integrity.  Sound or pictures often 
remain intelligible despite a certain 
amount of lost or disordered data 
packets (which appear as static).

IP address of the MultiVOIP.  For an IP 
address to be displayed here, the 
MultiVOIP must have DHCP enabled.  
Its IP address, in such a case, is 
assigned by the DHCP server.
