It seems that you just copy the specification of clarent gateway from clarent home page.
What I have asked is the one you have is analog or digital (E1/T1) gateway? How many ports does it come? Apart from the WinNT is there any other software? How about the Command Center?
Please be more specific on the gateway package you want to sell.
Thanks in anticipation for your reply. Mail me at firstname.lastname@example.org
