host, grandstream is the second-level domain, and.com is the top level domain.

FXO

Foreign eXchange Office

An FXO device can be an analog phone, answering machine, fax, or anything that

handles a call from the telephone company like AT&T. They should also operate

the same way when connected to an FXS interface.

An FXO interface will accept calls from FXS or PSTN interfaces. All countries

and regions have their own standards.

FXO is complimentary to FXS (and the PSTN).

FXS

Foreign eXchange Station

An FXS device has hardware to generate the ring signal to the FXO extension

(usually an analog phone).

An FXS device will allow any FXO device to operate as if it were connected to

the phone company. This makes your PBX the POTS+PSTN for the phone.

The FXS Interface connects to FXO devices (by an FXO interface, of course).

DHCP

The Dynamic Host Configuration Protocol (DHCP) is an Internet protocol for

automating the configuration of computers that use TCP/IP. DHCP can be used to

automatically assign IP addresses, to deliver TCP/IP stack configuration

parameters such as the subnet mask and default router, and to provide other

configuration information such as the addresses for printer, time and news

servers.

ECHO CANCELLATION

Echo Cancellation is used in telephony to describe the process of removing echo

from a voice communication in order to improve voice quality on a telephone call.

In addition to improving quality, this process improves bandwidth savings

achieved through silence suppression by preventing echo from traveling across a

network.
