[cisco-voip] Call terminated while leaving voicemail

[Mike Armstrong]

I finally found a credible witness; a summary of everything I know now is: 
Unity interrupts the caller with the normal end-of-message prompt ("To send 
this messsage, Press 1...").  Pressing 1 results in no message in the 
recipient's inbox, so Unity is apparently not seeing any audio. The CDR 
shows an origCallTerminationOnBehalfOf code of 12, indicating the caller 
hung up.  No error messages appear in any event logs on Unity or any 
CallManagers.  This happens with on-net calls.  This also accounts for 
several complaints I've gotten saying a caller claimed to have left a 
message, but  no message appeared in the client's inbox.  I'm off to TAC, I 
think.
