# Dialogic® NaturalAccess™ Video Access Toolkit 3G-324M over IP Developer’s Manual

The Dialogic® NaturalAccess™ Video Access Toolkit 3G-324M over IP Developer’s Manual describes how to use, install, configure, and run extensions to Video Access 3.3 that enables the 3G-324M over IP feature. The 3G-324M over IP feature supports the following functionality:

- H223 framed with NbUP over RTP for the bearer data

- BICC and Bearer Control Functions for signaling

BICC and NbUP are typically used in a 3GPP Release 4 (or later) core network. By supporting these protocols, you can terminate calls in the core IP network and use Video Access to develop advanced multimedia applications such as Video RingBack tone and IVVR.
