My work has an Avaya one-x communicator. I have set up the phone in the past to call my cell phone instead of my desk phone. I was in the office one day and used my desk phone. Since that time the desk phone will not transfer to cell. I have had all tech people in company look - they say the Avaya is set up correctly. I had changed some settings on my phone, but can't seem to find what I may have done. PLEASE HELP!!
