The 'Impact SCS Phone' page from Comdial says no.. https://www.comdial.com/telephones/impactscs.asp The flyer from that same page says yes.. https://www.comdial.com/brochures/impactscs.pdf 1/2 the dealers in the country I talk to say yes the other half no. Calling Comdial, I get 2 different responses.. Its a deal breaker (the 8412s are just too expensive in the volume we are looking at) Any ideas? _Joe

The "F' at the end of the model number (but before the color id)on 83 and 84 series phones is for full duplex. And you need a to have the right software level for the system that you are using the phone on. Common code software needs to be 12A or higher. Common code is DXP,DXP plus, and FX [This message has been edited by CMDL_GUY (edited February 20, 2004).]
