I'm looking for some more documentation for the SPA50x (SPA502g exactly) and its Programable Soft Keys.
I want to build a button that will start a blind tranfer with a *9 in the beginning of it and allow the user to press another 3 digits, and another soft button that will do an attended transfer, wait 4 seconds and complete the transfer.
This also might be more complex than the PSK allows without going into XML Apps. If that is the case a document on getting started with that would also be helpful.
Thanks.
