Softphone not loading in visual force pages

We have created a custom visual force page (unmanaged) where softphone is not loading. We are getting the below error while opening the visual force page

Uncaught SecurityError: Blocked a frame with origin "https://ap2.salesforce.com" from accessing a frame with origin "https://c.ap2.visual.force.com". Protocols, domains, and ports must match.

However, softphone is successfully loading on other tabs such as Home,Contacts,Accounts etc. We have ensured that the open CTI call center file is assigned to the user and sidebar is set to true in visual force page.

Can anyone help me on this

This seems like a cross domain issue that the browser is running into. Are you using the service cloud console? Are you also getting an error like "Service Cloud Toolkit API cannot be used with your browser."?

Hello, 
Searching on "Service Cloud Toolkit API cannot be used with your browser" and came across this post. Sonam, is this a general failure reference of some kind or is it soemthing specific? We are attempting to install the open cti connector for Avaya AES and getting this error. 
Thanks.
