Hi everybody: We got a new IP 1230 series phone (Avaya). I provisioned a new extension and hooked it up. Everything came up as expected. But, when I picked up the handset to make a call, nothing happened. If I pressed one of the extension/intercom buttons, the speakerphone came on, but nothing through the handset. I thought that maybe the headset setting was funky, so I tried to adjust that, using settings 1 2 and 3 with no dice. Am I missing something in the configuration, or do you think this is a defective phone set? Thanks everyone.
