How outgoing calls are supported through CURRI

I understand that we can DISPLAY NAME BASED on CALLING NUMBER for incoming calls via CURRI

Questions :-

1. What all CUCM version does CURRI supports to DISPLAY NAME BASED on CALLING NUMBER for incoming calls , please specify ?
2. How outgoing calls are supported through CURRI ?
3. Do CURRI supports Outbound calls while DISPLAY NAME BASED on CALLED NUMBER ?

1) Calling/called name modification is supported as of CUCM 10 and higher:

2) As far as CURRI is concerned calls are neither incoming or outgoing: any call - whether originated by a device or arriving by a gateway/trunk - can trigger a CURRI request as long as it matches the corresponding translation/route pattern or DN.  Note: CURRI apps cannot originate calls to a destination on their own

3) See #1 and #2 above
