[Asterisk-Users] 302 "Moved Temporarily" clears Caller*ID

[Eric Wieling]

When Asterisk receives a 302 "Moved Temporarily" response Asterisk 
correctly forwards the call to the new extension, but the ${CALLERID} 
info is lost. Cisco 7905 sends this message when a call comes in and the 
user presses "ToVM" button on their phone.

Also the ${DNID} and ${RDNIS} variables are not set or are cleared.
