I recently installed a UC500 for 5 users. The setup has 3 7921 wireless IP phones and 2 analog phones. The setup is such that the main extension is on an analog phone so that if the UC500 is down, calls can still be received from the PSTN. My problem is that I don't know how to setup the call transfer from the analog phone which has the main extension. Also there is no option to change how long the phone rings before a call is diverted to the voicemail when using the configuration assistant for the setup. I am not used to the command line interface!
Thanks for helping
