You can do whats called: direct connect (coliquial "chirp") which is a trunked individual call.. you can do talkgroups which are like having a radio dispatch channel, and you can do group calls which are essentially one time on demand talkgroups, but in most cases is limited in the number of users that can be connected, normally about 20.
Your not dialing, per se, your entering the radio id number you want to alert. In my radio system its called a LID or Logical IDendtification number others like Motorola call it a RID Radio IDendtification number and in essence thats what a DC number is a RID since iDEN was developed by Motorola.
If I authorize it radio 1234 can "individual" another radio such 4321. Its much quicker than a phone call, and once you have the DC#/LID/RID you can store it and pick your contact on from a list... hit the PTT button.
PTT is like having a NATIONWIDE and sometimes INTERNATIONAL radio system.
It helps to not thing as iDEN as phone network but a very advanced FRS radio, VERY ADVANCED.
