Byte Level Messages 5-58Issue 6 June 1997 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) Byte Description Byte Value Comments Length of the IE 0x01 or 0x02 Ext bit | Party ID 0x??
