CLI stands for Caller ID. Caller ID is a significant feature in VoIP. Caller ID is when calling to another phone, your number will appear in Caller ID so they can recognize it is you.
Typically when calling locally in your country, you do not need to be concerned about caller ID because it is something that is guaranteed. When calling internationally, you are not definite the CLI feature thus it is the responsibility of the wholesaler to check thoroughly. In VoIP wholesale termination, one can decide to allow CLI routes or to not let them. Generally for termination providers,CLI routes are more expensive than non CLI as a result they choose non CLI for the reason that customer always wants cheap rates with good quality.
Consider that,CLI has nothing to do with voice quality at all, it is just a particular feature that some try to supply. Consequently, customers just want good quality and CLI is not very important. As a result termination providers just give the non CLI route because it is low-priced.
If you are a wholesale termination provider, in that case it is necessary to know whether your CLI route is pure or fixed. The difference between the two is to some extent important when choosing the routes to supply. Pure CLI means a full caller ID which is go through to the caller where a fixed CLI means a lesser quality CLI is provided.
This is only the choice of the provider. End customers such as you and me, do not complain as much about this feature as actually we only care that we get a good connection. So, if you find a cheap calling card that gives such a feature then by all means go for it.
