[asterisk-biz] follow me extension id?

[Lang Hunter]

hi all
say a client has 4 incoming did's diverting to a mobile phone through 'follow me' if unanswered in the office, is it possible to know which initial number was called?
for example, say he had 4 dids from different countries, would if be possible to have a prefix id arrive on the mobile depending on which number was initially called, prior to the callers number?

cheers
