Re: Status Code = 0x10 on unanswered call

Allen,

The "destination" can't release without answering if it's a POTS
line (plain old [analog] telephone service).  By definition you
have to be off hook to go on hook.  This also applies to T1 E&M
intermachine trunks.  An SS7 ISUP or ISDN Q.931 signaling system
can initiate a release before answer.  H.323 endpoints use Q.931
call control so they are included in that number.

The normal scenario is that the call remains in the alerting stage 
(if it got that far) until the caller abandons the call.  That is 
what you should expect to see.  That is what you will see.  If you
see a release from the destination end end it's more likely coming
from a switch in the circuit switched network or a gateway.
