In the REST environment to communicate with Twilio, I have written:

a REST client which makes a request of Twilio, and,
a single resource REST server which provides for call processing and relies only on a Twilio API. Although in the C5 folder structure, it doesn't interact.

Now, I need to capture the call status from Twilio and update a C5 custom table with that status. But, since this program is running outside of C5, I need to recreate an environment for the limited amount of interaction needed.

The simplest way seems to use a bit of ADODB and the existing C5 DB infrastructure -- providing logon, connection string, connection handle etc. -- as well as any appropriate defines along the way.

(It seems that setting up a new connection might be as much if not more costly than going through the C5 overhead.)

So, a C5 instance starts up in concrete/Dispatcher.php. Naturally, DB access comes pretty soon in the process, after a number of defines and checks. It seems that support for PHP time functions as well as time zones would also be useful, and users. Anything else?

I will be sorting through this today and will post my results, but if anyone has any suggestions to assist my trial and error, that will be appreciated.
