They are two different critters and we’ll have a class on Voice over IP business telephone systems so you understand that better.
We talked about the trunk lines which are used in business phone systems. So the trunk lines, however many trunk lines you have, are how many concurrent communications that you have with the outside. So every incoming call uses a trunk line.
Every outgoing call via your business telephone system uses a trunk line. So if you have four trunk lines and you have four incoming calls, you are not going to be able to make any outgoing calls. If all your sales people are trying to make a lot of calls and they’re calling out, you have four trunk lines and you have four of your sales people calling out, then nobody can call in through your business phone system.
