Placing a Test Call from VCS
Yealink Demo1 to Yealink Demo3 are three default contacts stored in the local directory.
You can place a test call to the default contact, and the test call will be routed to the Yealink
demo video conferencing system. Yealink demo contacts can help users to test quickly whether
the system is normal after installation.
