I am implementing a SoftPhone using OpenCTI.

In OpenCTI the SoftPhone is displayed in the SalesForce sidebar using an iFrame.

However, when I change focus in SalseForce for instance I am on the Contacts page and I click on the Accounts page the iFrame including the SoftPhone gets reloaded and I lose the state of my softphone.

Is there a way using OpenCTI API or another way to not lose the state of my SoftPhone on a SalesForce page reload?
