Abstract
A method for providing supplementary services in a packet voice network. The method includes the steps of receiving a list of information elements from a sending station and then inserting the list into a call control message. The message is inserted in such a manner as to ensure that any supplementary services information included in the information elements is preserved. In addition locally significant messages are included in a globally significant message so any supplementary services information in the locally significant messages is preserved. After the supplementary services information is preserved, the messages are sent to a receiving station. A network device operable to provide this functionality is also discussed.
