Hi,

I have a TDM400p asterisk board and i have two questions.

  1. Can i make money with this by doing some business with it? If so How?
  2. I 'll normally use my IP phone or Landline phone to call to my business partner in abroad and if i use this TDM400P asterisk board whether it will reduce my telephone cost or not? If so How?

please do help me…

Thanks,
KMK
