I have a mj... I have used it for voice and fax both... It was great at first. lately I have been having major issues with the quality of the line. I have tons and tons of static at times other times its perfectly fine... since these line quality issues I have been unable to fax. it calls rings scans then wont send anything. i have no clue what is wrong.
I did the repairs and re dl the software. nothing fixed the problem.
what I have done is to have the mj # forwarded to my cell phone. If I am near the pc and the mj is working I call the person back from the mj. if its not i just answer it on the cell.
all in all I have had it for about 9months. I cant decide if I could recomend it to someone or not. the best feature is that I can call my mom who lives 12 hrs away and talk for free to her. sometimes tho i have to call her back due to static or we totally get disconnected for no reason. but hey its essentially free so I do still use it.
I can definatley say that I would NEVER depend on this phone to run a business.
