[asterisk-dev] Is this a "bug" or a feature?

[Alan Lord (News)]

Hi,

I apologise in advance for jumping in on the dev list but it seems as 
though ${EXTEN} is not being updated if the final leg of a call comes 
from within the dialplan (i.e. not user entered digits). The 
"Destination" record continues to read "s" even though a call is 
connected to a physical extension such as SIP/101. The "Destination 
channel" is correct but there is no, apparently simple way to get just 
the extension number of the b-leg of the call.

See this thread on asterisk-user I started a couple of days ago.
