Freeswitch and Callcentric

Have an existing Freeswitch application running on Cent OS5 with a Sangoma card. Uses Callcentric SIP for internal testing of new code . Have a backup machine to this server. I use Dropbox to keep files in synch on both machines. Backupo machine MB died, so have replaced it loaded Cent OS 5, and all supporting software. Person who configured original machines is no longer available. Issues are: Backup machine can not register with Callcentric account. Sangona card issue. Looking for individual with direct experience in debugging issue with these specific components. Looking to hire someone right now, as the backup machine needs to be PCI compliant for processing credit cards. You will only deal with the Callcentric and Sangoma card issue.
