I have a client that is trying to do a Service Cloud/CTI Integration using If By Phone

If By Phone uses a php page as their page in the phone panel and said they can host a VF page via IFrame to display a custom information within the phone panel

We are trying to use the Service Console Integration Toolkit to open an Account or Contact page as Primary Tab in a console from link. The issue that we are running into an issue the service console function is throwing an error which I believe is due to regarding cross-domain interactions.

Is there way to do this or can the Service Console Integration Toolkit be used on directly on If By Phone php page?
