Is there a way of offering Skype access to incoming calls while keeping all telephony traffic over our chosen business telephony provision? Is there a 3rd party who can route incoming Skype calls to our telephone system?

The business has had requests from contacts wanting to call us via Skype, but we want to keep all telephony via our PBX and phone lines as our geographic location limits our available internet bandwidth. We also prevent installation of non-standard applications on desktops and do not want to add Skype to our build.

I was wondering if there were any 3rd parties that provide a connection service that would allow our contacts to call via Skype and us receive the calls via our phone system.
