Summary:                    Exchange AutoAttendant cannot make calls back to
asterisk (worked in 1.6.2.2 + 1.6.2.6)
Description: 
When someone calls in to the exchange auto attendant they can say someones
name and it will dial the correct extenstion.  This worked fine in 1.6 but
does not work in version 1.8.0.

In the example below the call came in from 3174999999 (masked real number)
was transferred to 888 (exchange um) and then exchange um tried to transfer
to extension 501 which failed.

---------------------------------------------------------------------- 
Transferring directly to voicemail was fixed by changing my dial plan
from:

exten => _*11XXXX,n,Dial(SIP/EXUM/8800)

To:

exten => _*11XXXX,n,Dial(SIP/EXUM/8800,10,TtWw)
