To connect to an external number or to place an outside call a trunk access code is normally pressed like 0 for operator and overseas/ international calls, or 9 for local calls after which if given the tone you can dial your outside number directly. A department normally has 2 to 3 trunk lines based on call volume load and other specific criteria. Normal features includes forwarding, conferencing, call pick up groups, intercoms and transferring. In a telephone company, one has to pay separate for these features, but with PBX everything is already built in.

A gateway is needed to communicate with others within the network. In some locations like MO in Saint Louis, New Jersey and Ohio office, they are already using an upgraded VOIP like a CISCO 10mb Hub.

Disadvantages:There is a time delay incurred in routing calls from the central box to the trunk lines. Somehow if the customer knows the local number they aim to eliminate seconds of the delay by automatic elimination of an operator use. If we go on a recording voice first for the identification of local trunk lines, we tend to test the patience of our callers and of our best customers who would want trucking services that are literally fast movers in every sense of the word. Susceptibility to tapping is very liable when it comes to unguarded PBX installations.

Disclosure of and unauthorized recording of information by eavesdropping from the central box and routing of address data made possible thru unauthorized access including data modifications. Emergency dial is not accessible. There is a big difference in using a PBX phone line than a regular phone line for it needs to be routed to the central box before it gets to access outside lines.
