Gateways in sipXecs 4.0: Part 1

[ Thanks to sanjay

“Gateways provide the connectivity required to reach
other systems. These systems can be other sipXecs PBX’s,
traditional phone lines, or Internet Telephony Service Providers
(ITSPs).Connecting the IP phone system to the outside world is one
of the most difficult tasks in making the phone system work. If the
network infrastructure is configured properly for quality of
service, the connection to the outside world can most likely be the
source of any call quality problems.

“Traditional analog Plain Old Telephone Service (POTS) lines are
the largest source of frustration. If you can avoid them by
utilizing a digital type of service or an ITSP, by all means take
that avenue. For those not so lucky, you’ll learn more about them
then you ever thought you needed to. Typically, volume levels, line
disconnect, and echo are the most common problems. Most gateways
will have some advanced settings for dealing with these issues but
they are different for every manufacturer. Adding gateways

“There are three types of gateways that can be configured to
work in sipXecs; managed, unmanaged, and SIP Trunks. A managed
gateway is a hardware device that connects to a traditional phone
line. sipXecs knows how to generate configuration files (plug and
play) for it. An unmanaged gateway is either a hardware device for
which sipXecs doesn’t know how to generate configuration files, or
it may be another SIP PBX. A SIP Trunk is a connection to an
ITSP.”
