Course 110: Media Gateway Control Protocol (MGCP) Fundamentals - TONEX.com

The 2-day training course: "Media Gateway Control Protocol (MGCP) Fundamentals" provides in-depth coverage of VoIP and MGCP.

Media Gateway Control Protocol (MGCP) is a protocol used for controlling Voice over IP (VoIP) Gateways from external call control elements. MGCP is the emerging protocol that is receiving wide interest from both the voice and data industries.

MGCP and Megaco / H.248 are control protocols designed to be used between a Media Gateway Controller (MGC) or call agent and a media gateway (MG).

After completing this course, students will be able to:

• Explain the basics of MGCP
• Review of Session Description Protocol (SDP)
• Explore MGCP Commands
• Explore MGCP Messages and Parameters
• Understand differences and similarities between MGCP and Megaco/H.248
