psichel,
Hi,
I'm not familiar with your product, however If OBi had a Mac version of their OBiApp and if your product had sip softphone ability, you could use their OBiAPP middleware software to do pretty much all of what you are asking. This could give you another approach, one perhaps you had not yet considered. From your comments, I can see that your mindset is on using a modem rather than SIP approach.
People have requested a Mac version of the OBiAPP. Third party developers like yourself add a lot of value to the OBi unit. Perhaps the fine people at Obihai are currently working on supporting the Mac, or perhaps you can convince them of doing so.
I checked out your web page. Very interesting product. Too bad you don't have a windows version, I certainly would be a customer.
The folks behind Obihai are usually very responsive. I'm certain that if you seek out Sherman with this opportunity to piggyback on the OBi, he would be a good resource person for you.
It's exciting to see how the OBi can be used in a day to day basis using some of the more requested features on this board, and some of your innovative call integration features. I can't wait to see with what you come out with. I will be envious of the people who are using the Mac.
