Still need help or information, as stated in my other requests, Why none of the extentions can place a CO call on hold, or SYSTEM HOLD. How can this be done, also 2nd question: No matter the programming changes, some extentions we can not establish RINGING for incomming lines. For Exp: Ring In: 1.1-10.6 or type "ALL" - also I have set this command for day & dight ring. Some work, some just don't ring ???
