Which means rewriting zaptel.conf to fit the new configuration or
writing a new zaptel.conf just for the new span. Otherwise it will
probably fail. You also need to actually pass that information to 
userspace.

Right now Asterisk will badly crash on startup if it has any unmatched
zaptel channel in its configuration. Adding a channel or changing
anything in their configuration requires a full restart of Asterisk.

So if channel numbers happen to move, you need to rewrite the
configuration. If you want to plug in hardware and have it work, you
have to generate zapata.conf in an automated manner.

There are some settings for which you can give reasonable defaults on
the top. But for some you just have to give new values at some channels:
caller ID, context.
