Ringing

[fernan05]

hello
I need to be able to distinguish the ringing of the porter calls with calls from internal users; As well as to distinguish the ringing of incoming calls on analog trunks, from incoming calls on IP backbone or incoming calls of ISDN.
I watched the table Ringing of the Noteworthy Addresses, but I did not found the solution
This is possible?

thanks in advance
