I just received a shipment of 7940s, 7960s, and 7970s but the Callmanager and Unity servers have not yet come in. I would like to replace the current analog phones on the desks here with the Cisco phones and use the existing PBX via the analog port on the back of each phone. I have searched extensively and played with the phones for a while now and have come up with nothing. Anyone out there know if this is possible and if so, how to do it? Thanks in advance.
