1) moved to "goautodial" board, as this question regards installation onto a specific OS, and CentOS is not supported by The Vicidial Group, but it is supported by Gardo of GoAutoDial and a few others who pay attention to THIS board.
2) your question is more along the lines of "how can I make this 'pika' card work with Asterisk, after you do that we can help you make it work with Vicidial.
3) please post the model number of the card you are installing
4) did the manufacturer or manual for your card list asterisk configuration at all?
5) welcome to the party! a couple notes: ALWAYS list your Vicidial Version with Build (on every post) (should be something like: Version 2.2.X build XXXXX-XXXX. Also post your installation .iso name with version (I will assume GoAutoDial 2.0CE, please correct me if i'm wrong
). Also listing your asterisk version (available by entering asterisk -R at the command line, list the entire version not just the X.X portion!).
