| Help! I am thoroughly confused as to how this phone system works and I've got a million questions. I have spent some time on Google trying to find the answers but can't. Our vendor says that we can only add IP phones as we are out of extensions? How can I verify this? Is the number of extensions tied to how many cards we have? How many extensions can you have per card? Are there analog and digital cards or just analog cards? How do you swap an extension? Say user A is moving to user B's desk and wants to take her extension with her. How do you do that? So the punchdown block is like a huge router? 10 lines come in from the phone company but somehow are shared by the phone system and our 300 extensions? Thanks in advance for the help. |
