This time I did some digging but couldn't find a solution LOL. I'm not even sure the 9000 / 400 does this. With the client's key system they had 4 line on each phone. One line was for their extension and the other 3 were outgoing PSTN lines. You could see if a line was busy. Is there someway with the 9000 / 400 to associate an extension with a spa 400 DID line so they can have their outgoing lines on their ext 2,3, and 4? I have them setup to dial 9 and then it rolls to the 3 lines but I was just curious if you could use shared line appearance with lines off the spa 400. Thanks.
