Cisco CVOICE 8.0: Transporting Voice over IP networks
This course is included in our On-demand training solution.
H.323 gateways are among the most common Cisco IOS voice gateways within Cisco Unified Communications Manager environments. H.323 gateways are the endpoints on a LAN that provide real-time, two-way communications between H.323 terminals on the LAN and other ITU-T terminals on the network. H.323 gateways can also communicate with other H.323 gateways. Gateways enable H.323 terminals to communicate with terminals that are not H.323 terminals by converting protocols. Gateways are the point where a circuit-switched call is encoded and repackaged into IP packets. Because gateways function as H.323 endpoints, they provide admission control, address lookup and translation, and accounting services.
The inherent characteristics of a converged voice and data IP network present certain challenges to network engineers and administrators in delivering voice traffic correctly. This course describes the challenges of integrating a voice and data network and explains the technologies that enable voice media transmission.
The target audience for this course is established IT professionals with a solid, existing background in Cisco and networking technologies.
