Hi, I have been working with Cisco VoIP since 2001 and Asterisk and freepbx ,trixbox, elastix since 2007. I'm very new to the site so trying to bid as low as possible and get better reviews as much as possible. That being said kindly let me know what time suits you so that we can discuss the project in a little more detail. regards,

Hi, If the numbers you wish to test are only mobile numbers, then I can help you. I think you did not write price per check correctly. The minimum I can find is 1 cent per check, not 0.1 cent Let me know if interested. Thank you Regards

I use to own my own VoIP company and I had this same issue... I know what its like to have provider charge you for phone number called that does not exist. I created a tool for asterisk 1.2 and I can write it for the new version
