I am new to the CCNA voice world. First of all, I come across to the ISDN switch type in some website, but I still cannot get the clear picture of this concept. May I know where I can get the ISDN switchtype that to be used in our voice network environment and why do we need to use this switchtype?
The only way to know for sure what switch type to configure on your side is to ask the other side what they are configured for. Most providers use the terminology 'ISDN protocol' or 'ISDN protocol variant'.
Note that you can run a 'national/NI' protocol on top of a physical 4ess, 5ess or DMS100 switch so you need to be specific in the protocol variant running, and not what physical type of switch it is terminating on. In my experience, national is the most common, followed by DMS100. ATT circuits are often 4ess or 5ess.
I always ask them what they have provisioned. I never phrase it as 'are you configured for XXXX' because often they will just respond with 'yes' instead of actually looking it up. Phrasing the question in the former format forces them to actually look at the configuration.

the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
