I am new to Asterisk and need help putting the pieces together. I have a Yealink T28P phone and I’m able to connect it properly to Asterisk. My question is a more about the fundamentals of assigning lines and extension to the phone.
With a traditional PBX, I would have buttons on the phone to indicate the POTS lines and when I wanted to dial out, I would choose the line that is available. Conversely, if a call came in, I would see which line it was and answer the call.
For the purpose of my question, lets assume I have 2 POTS lines, 2 SIP lines and 5 office extensions. How would I go about configuring the phone. Do I need to move away from the old thinking and just assume that Asterisk will handle the call based on a dial plan and all I need to do is pick up the phone and dial?
The Yealink has a facility to assign 6 SIP accounts, but they in turn relate to an extension number in Asterisk. How does that fit together. Do I assign extensions to the users (1001 - 1005) and separate extensions for the SIP lines (2001 and 2002)
I would obviously need a FSO/FSX card for the POTS lines but how do they get linked to the phone? Is that all done for me by Asterisk?
I hope my question make sense - just want someone to give me a quick overview of how to set up a basic system - or point me to a good article/post.
All help is greatly appreciated
