Wow. This list is high traffic.... Just to add to the noise, here's
some of my extensions.conf that implements what you are talking about.
In particular, the macro "featureexten" takes an argument that is the
same as the context the user uses for outbound dialing. The result
being that whatever number the user puts in the CFIM database is
dialed in the same way that it would be if the user dialed it directly
from their telephone. It is used like this:
exten => 5551212,1,Macro(featureexten,usercontext,SIP/whatever,${EXTEN})
Normally [usercontext] will include => [features]
Of course beware that this is only accessible from lines that have their
callerid forced to something reasonable, else you can steal lines...
