[Spce-user] NCOS and Block list patterns

AFAIK the difference in syntax is mentioned in the docs or at least in the hover-notice in the panel.
I have no idea why there is both but it's probably for historic reasons and I assume glob interpretation is way
easier and less costly (cpu wise) than full regexp.
Block lists are either allow or deny (Depending on block list mode) and so are ncos-levels (white- or blacklist)
We only use block_lists. We have different classes of forbidden number patterns that can be combined.
we then generate a complete list and set this list for the customer. (It can be selected by staff or customer via crm/webinterface)
In addition we use an adm_ncos to deny calls to satellite numbers and known fraud prefixes/numbers and a adm_cf_ncos (I think, maybe te name differs) to prevent call forwardings to emergency numbers/premiums/foreign.
I don't think you can do allow AND deny in the same list but we simply forbid everything we/our customer does not want to being
able to call and everything not explicitly forbidden is allowed by default.

Btw, can we make excludes from list?
Should we write few regexps to flow around or there is simpler method exists?

This puzzles me a bit - why they are different? Why not regex everywhere?
I think it worth to mention in docs about these differences - it's not so oblivious.

Block lists accept "glob"-format ( https://en.wikipedia.org/wiki/Glob_(programming)#Syntax )
while ncos accepts regular expressions. When there's a conflict between ncos/blocklist
(one explicitly allows while the other explicitly denies, default beahvious is to deny)

Is NCOS and Block lists really accept different pattern formats?
Can we use regex?
