This Recommendation provides two sets of packages: syntactic and functional. The syntactic packages provide the ability to specify announcements with variable content, with a degree of flexibility constrained only by the provisioning of the MG and MGC. This syntax may in principle be used to specify multimedia announcements, although its application in this Recommendation is to evoke audio content. The functional packages provide advanced control of an Audio Resource Function using the H.248.1 protocol. The packages provide the ability to play recorded announcements with variable content, carry out prompted collection of digits, and carry out prompted collection of recorded audio. An additional package provides the ability to manage recorded media segments on the Media Gateway.
Additional functionality incorporated by H.248.9 Revision 1:
• 126.96.36.199 New variable type "tone" for dynamic audio segment specification.
• 6.4 Set extension of basic syntax: introduction of a new selector for text attributes.
• 188.8.131.52 Variable type "Phrase": introduction of subtypes.
• 9.3.1 Signal PlayCollect: enhanced functionality, new parameters.
NOTE – This Recommendation has been renumbered in 2002. It was formerly known as ITU-T Rec. H.248 Annex M.1.
