I am using "My Sales Dialer" a mobile based power dialer application with my "Motorola Droid X MB810". Right now, I am using it with T-Mobile card. Its working good and I am making 150 calls by this dialer. Now I want to use Vonage with this dialer. Is there any way of getting Vonage service for free? This dialer is compatible with VoIP. is there any need of extra software or application with my mobile to connect with dialer??
