Let's not use "telephony" terms to refer to how computers (ie. data communications) work. It's much more convenient to say "connect" rather than "call".
A switch is merely that - a switch. It switches data from a "sender" to a "receiver" and vice versa. And switches tend to make sure that the data intended to a certain "receiver" will only be received by the "receiver" and none other. To answer your question - no, there's no other way to "cut it short". You need to connect your 5 Ubuntu machines to their own respective ports on the switch (1 switch port = 1 UTP cable = 1 Ubuntu machine). Then you need to assign an IP address to each of your Ubuntu machines. An IP address acts like a "phone number" if you will. Or more ideally, treat an IP address as a "street" address, which allows computers to identify each other. A computer with IP address 192.168.0.1 belongs to the network 192.168.0.0. And each of your computers must belong to the same network (or subnet) in order to be able to communicate (connect) with each other. If you do not want to assign each Ubuntu machine an IP manually, you can use a DHCP server to do that for you. One of your Ubuntu machines can act as your own local DHCP server.
