NOTES:
There must be the same number of Party ID IEs as there are Connected Number IEs.
The Nth Party ID IE corresponds to the Nth Connected Number IE (and thereby 
associates an extension with that party).
To preserve a 1:1 correspondence, if the type/address for a party is unknown, a 
Connected Number IE is present for that party, but the length byte is coded as zero 
(and no bytes follow).Acknowledgment of Third Party Take Control Request — (continued)

Call Control: RELease COMplete Messages Sent
by the Adjunct
A RELease COMplete message terminates an association on an existing CRV. All 
RELease COMplete messages have the Protocol Discriminator and the CRV 
followed by a REL COM type = 0x5a.
See “RELease COMplete Messages Sent by the switch and the Adjunct.”

Call Control: Internal switch Audit 
Finds Stale Call Control CRV
NOTE:
“Stale” in this context means that while conducting an internal switch audit, 
the switch has discovered a call control association with no corresponding 
call and terminates the association.
