I work for a company with 14 analog phone lines and about 40 phones. Our phone vendor is trying to sell us on an IP Phone system since our systems is outdated. We have a fairly small network, a few switches, a router to our ISP, file server etc.. Would an IP phone system use the switches we have or do they require new ones? Also would we be getting rid of our 14 phone lines from our local phone company? If so, where would calls outside our building go to? I understand how it would work inside our building, with everything running over our data network, but what happens for outgoing calls? Do these IP systems just use the analog phone lines, or does the phone company give us some sort of IP line(s)?
