I emailed the CallConnector Team about this and they said there are no plans to support the dial plan and I would have to use the UCC client. I have the UCC client and it works, which is why I was surprised the SCC Toolbar did not work. It's missing the Dial Plan Tab. So, it looks like they confirm what you say as well.
It's not clear that adding the access code to the toolbar is necessary. That part should be bold and repeated several times. It's a huge shortcoming and a common sense functionality. I'm glad it's there using the Call Contact, but I would only use that if, say, I wanted to select another number of the contact -- perhaps their mobile phone. Most users would click the contact and expect to be able to dial out right away. It's seems a little strange to me not to put in the functionality of the dial plan so that I can actually click-to-dial.
Right now, a user has to click, move their mouse to the toolbar, add the access code, then click dial. So it's not really click-to-dial. Again, I just think it's a huge shortcoming for the product -- free or not. I mean, who designs this with the intension of making the user put in the access code. You would think the product would be released with its funtionality in mind: Click-to-Dial. Surley the product designers didn't ask a user to try it. It's painful to try and explain to a user to add the access code. Not good enough in my opinion. It's just plainly ridicuolous to omit it.
Thanks for your comments.
