[This has come up a few times over the last 4 years on this list and
others, but it has never before had enough people look at it who
understood perhaps what the benefits were, so I drag it out again
here for your amusement...]
Would a CSTA interface (or in a variant, uaCSTA) be a useful API
layer for Asterisk? Would some of the PineMango goals be workable
with a CSTA method as the "language" portion of the communication?
Or would it merely be a monolithic module that would talk to the API
components as a discrete consumer/producer of messages to the various
components? I'm largely ignorant of the details of where the API
discussion would layer into what something like CSTA could offer -
feel free to say that these two concepts are non-intersecting and
I'll drop it.
Regardless of CSTA's role in a potential "next-generation" fruit-like
API project, it still bears examination as a potential interface for
other Enterprise-ish platforms. Microsoft's OCS/LCS Platform uses a
variant of uaCSTA over SIP, as does Avaya, Cisco, Mitel, and
others(?- need a list). Of course, I'm not so interested in those
legacy PBX platforms, but the tools that third-party companies are
producing to bolt onto them are what sound like has some value.
Creating a CSTA interface to Asterisk would allow quick grafting of
"industry standard" tools onto an inexpensive and flexible OSS
