I don't know much about it, but when our office telecoms system was replaced a few years back, it then included this kind of functionality. I can (or could, when I was in the office) have an exchange toolbar that allows me to control my phone, including call forwarding behavior. I don’t think the API was public, but as I understood it what was actually going on under the covers was the plugin was talking to a local server/service, which sent commands up into the telco cloud. Between them the different telcos must have dynamic peering arrangements, because it could fwd my desk phone to my mobile seamlessly, complete with caller ID and everything (and the company picking up the charge differences between landline rates and mobile rates IRRC)
So I think the first thing to find out is : what is their call system? It's more likely you'd be talking to that than to Telstra direct (I'd have thought) From: Mark Hurd Sent: Tuesday, December 16, 2014 6:00 PM To: ozDotNet On: *21<forward number># Off: #21# -- Regards, Mark Hurd, B.Sc.(Ma.)(Hons.)
