Chapter 4 - MultiVOIP Software
Viewing Statistics
The Statistics dialog box enables you to view statistics for major events of the MultiVOIP operation.
This dialog box is accessed by clicking on the Statistics button on the Main MultiVOIP menu.
Statistics can be a helpful troubleshooting tool. For example, viewing the Voice Channel statistics
you can see the attempted and completed calls, call duration, average call length, bytes/packets
send and received, and so on.
IP Statistics
IP is a connection-less network protocol residing in the network layer of a conventional OSI layered
model (for more information on this model, refer to Appendix A). Depending on what is going on at
the application layer, IP will typically use one of two transport layer protocols. User Datagram
Protocol (UDP), a connection-less transport layer protocol used with TFTP or SNMP; and Transport
Control Protocol (TCP) is a connection-oriented transport layer protocol used with FTP, Telnet, and
SNMP.
UDP makes use of the port concept and has no measures for flow control, reliability, or error
recovery. It is used when the full services of TCP are not required, and the reliability measures must
be assumed by another layer.
TCP works well in environments where the reliability measures are not assumed by other layers. It is
connection-oriented and has a full range of services.
