[Freeswitch-users] hardware requirement to run voip application

Hi to all, I dont know, whether I can post this question here or not, I dont have any other options . I hope some one will help me here. Here is my question? 1. I have developed my voip application on top of freeSwitch, Its working fine with soft phone. 2. Now, I need to test my application by calling my landline. I am living in India. I did some googling, I got to this hardware, *Linksys SPA3102 *. Is this only hardware enough to run my voip application or need more hardware? I am very new to this platform, and not having knowledge on hardware. Can anyone please suggest me which hardware which is freeswitch friendly? -- Regards Venkatesan OV.
