I have a Cisco SPA504G that I am using 1 line with another service provider (Callture) and I am trying to setup Obi202 to be used on the same phone. I am not an IP phone expert so I am not sure how I can get both numbers through the same device. I have looked over the "Configuring an OBi Voice Service Bridge to connect a legacy IP Phone" document and not sure how to proceed. Is there a simple step by step guide to set that up? Is there a service that would that that up for me? Thank you in advance.
There is a limit to how simple something can be. What you are after is relatively complex and the document you already have is about as simple as it could be.
