Is it possible to initiate a Conference call from a SLT on a CIX 670? Just wondering if there was a command string you had to enter, or is the only way to initiate the call using a phone on a digital port and conference the SLT too. I have a customer that bought a fancy conference phone and they really want to initiate all the calls from it. This has me baffled, but it is not the first time....or the last I'm sure! Thanks, Jamie
