it is kind od 'self-legal' routes, for example when people in china
terminationg to france mobile through china telecom - it is grey route. 
no warranty that this route will be alive after month, no warranty on
quality (ASR and PDD).
in most cases caller id translation is impossible

another kind is mobile termination over SIM cards, when GSM operator
can close them at any moment - it is also grey.

'white' route - legal route with good E1 interconnect, but usually with
SS7 and with premium internet for voip.
