I'm in the process of setting up a 3CX v9 system for approx 18 users, using Polycom SPIP 450 + 650 handsets and I'd love any advice or tips on setting the handsets up. We're primarily using Polycom handsets as the husband of the director of the business works for Polycom ;-) Now I'm happy with setting up DHCP reservations for their MAC addresses, assign correct DHCP option 66 settings, and provisioning the hansets via the extension and default templates. Following guides on here I've allready tweaked the 'linekeys' setting. Something that I'm not happy about, and I'm hoping that this is not something we're stuck with, is that after dialing one of our four figure extension I then need to press a button on the handset to 'send' the call. Should it not just automaticaly dial the extension ?. Thanks.
