Avaya Aura SIP Trunking Training

Transcription

1 Avaya Aura SIP Trunking Training 5 Day Course Lecture & Demo WHO NEEDS TO ATTEND This class is suited to those who are new to administering Avaya systems and would like to know more about the SIP protocol. This is not a class for marketing or salespeople; it is a class for administrators, architects, and engineers. COURSE DESCRIPTION Students will learn how to plan, implement, and troubleshoot the Avaya Aura SM and SMGR as needed to support SIP trunking. Students will learn how to use Wireshark to perform much of the troubleshooting and testing. Training is offered at the customer's site, online through our virtual platform, or at our training facility in Harrisburg, Pennsylvania. Telecom training classes can be customized to meet a customer's learning needs and scheduling is flexible. Contact us for quotes! 1.
