I just bought the LIP 9071 IP phone and am stuck as I can not register it. Please, I need urgent help as soon as possible. RE: IPECS 9071 NO ACK after registration sizbut (TechnicalUser) 12 Jul 19 06:39 Is your system configured to support SIP phones? Have you added an 3rd Party IP Phone licenses? Have you created a SIP Extension and associated user? What has the phone prompted you to enter and what did you enter? What type of IP Office and what release of software? Stuck in a never ending cycle of file copying.

You will need to make sure you have it set to DHCP and are using SIP.

You should be contacting your provider or someone qualified to help you immediately. In other words you should be paying for "urgent" support. The truth is just an excuse for lack of imagination.
