Quite a long time ago, population had to personally see each other to set appointments or to talk. Just fantasize how much of a hassle it was for them when sudden cancellation of appointments had to take place. We know, that is quite hard to fantasize given the technological advancements that we have now. We are probably born in the telephone era or have known how to use the telephone one way or the other. With the telephone, all we have to do is dial the estimate and it is very likely that you will get to talk with the someone you are finding for. As if that convenience was not enough, movable phones were invented.
With movable phones, we can make a call and eventually, even send an Sms message everywhere we are as most areas are within the signal coverage. To date we are again witnessing other evolution of transportation technology with the existence of trunk VoIp. Trunk VoIp is simply a relationship line between two ports, specifically, voice ports. It connects the two gateways, creating a virtual link that connects two telephony ports. The dissimilarity it has from the other VoIp products is that it utilizes the old-fashioned telephones and fax machines and connects these machines to a VoIp network. This is great if the buyer does not want to totally eliminate conventional telephone service.

On the other hands, other VoIp products do not use these conventional machines and replace everything with software and online controlling. Trunk VoIp gateways are commercially artificial and they come in circuit boxes. These 'boxes' are what you join together to turn the existing plain old telephone service (Pots) into VoIp.
