2.Feature Support by Platform This chapter describes high-level features and support for each feature by platform. This document is used in more than one Dialogic ® platform (software release). There may be information in this document that is not supported in a Dialogic ® platform. Table 1 lists the highlevel features of the Dialogic ® IP Media Library API software documented in this current version and lists the Dialogic ® platform (software release) that currently supports each feature. This table will be updated as a feature becomes available on a platform. For function support information, see Section 23.5, “Dialogic ® IP Media Library API Function Support by Platform”, on page 122. Note: Using the AMR-NB resource in connection with one or more Dialogic products does not grant the right to practice the AMR-NB standard. To seek a license patent agreement to practice the standard, contact the VoiceAge Corporation at www.voiceage.com/licensing/php. Table 1.
