Cisco Voice Over IP (CVOICE)
Cisco Voice Over IP (CVOICE)- 5-Day
Cisco Voice Over IP (CVOICE) lays the foundation for gaining hand-on skills and significant
understanding of packet telephony by presenting the technologies that are
common for Small to Medium, Enterprise and Service Provider students. The course also
teaches students how to use the available Cisco tools to find the information
needed to accomplish their everyday tasks. Since no two networks are alike,
this approach enables a student to apply the knowledge gained in this course
to their specific needs. Students will benefit from Hand-on experience enabling analog FXS and Digital T1 configuration to the PSTN. H.323, SIP, and MGCP are explained and configured in detailed lab scenarios. Gatekeepers and the Unfied Border elements are also explained in this CVOICE class.
