I have some questions that maybe someone can help me to understand:


1. In a business telephone system, is the PRI that is used the same as an ISDN PRI?


2. If so, is it exactly the same?


3. One a PRI, is there one channel per phone call, so you have a maximum of 24 phone calls per PRI?


4. How does the telephone system get the phone call outside the building to another caller?


5. If you have a DID line and want to FAX sensitive documents, is it secure? Should it be encrypted?


6. What does it mean when someone becomes a POP?
