How do I? I am able to get employees off site to call into the soundstation, I hit the flash button and dial out another number such as an audioconference. How do I then get the calls connected into one? 1. example..press 3392 2. outside callers call 869-3392 the are in the call 3. hit flash button 4. Dial another line to get an external call patched through 5. I have two calls but they are not both on the Polycom station? How do I patch them all in?
