Once I left the horrible asterisk way of jumping around and entered the structured python way of handling program flow, asterisk became attractive for actual development. Via agi we entered python which communicated with a twisted server that was logged on as an msn bot. This way we could do text2speech (msn -> telephone) and speech2wav (telephone -> wav file transfer in msn). This was a few years back, so I can only imagine it has become better and friendlier. We also used it program our automatic response mazes to program telephone games. Loads of fun. Doing it all directly in sine sounds even more pleasant, but I have no experience in that field.

Light on docs and examples, but very capable, and not dependent on asterisk. Feel free to come harass us on #divmod on freenode if you have any questions. Hi Phil,

Sine is another thing to check out. . Light on docs and examples, but very capable, and not dependent on asterisk.

Feel free to come harass us on #divmod on freenode if you have any questions.

It runs as a separate service which allows it to handle initiating and handling multiple calls in the same logic flow. It's a regular set of Twisted Protocol objects. As noted above, it has ridiculously little documentation (and with my blog offline, far less than previously), but it does tend to work reasonably well and is a lot less frustrating to work with than the raw AGI APIs I tried. Shtoom was interesting, but it never seemed to gain any traction. Seemed largely to be due to need all sorts of gnarly custom application-level stuff to do anything, meant in practice you had to use lots of custom fixtures from Shtoom to run anything. Freeswitch is an interesting Asterisk alternative. I've had people ask if I'd port StarPy to it, but I haven't had the need (no VoIP clients lately).

I'm not sure what its status is: http://divmod.org/trac/wiki/ShtoomProject There was a good writeup for it (circa PyCon 2004): "Scripting Language" My Arse: Using Python for Voice over IP: http://www.interlink.com.au/anthony/tech/talks/PyCon2004/shtoom-paper.txt There was Shtoom, but I guess that was VOIP, not telephony in the Asterix sense.

For your needs its should be a walk in the park.

Minimally interactive, the user may press a number to reschedule or something like that, so nothing super complex. I’m setting up a system to do automated event reminder calls.

I haven't played with asterix myself. ISTR that there are at least two other FOSS projects - a gnu one and some other one (have a look on freshmeat.net, that's where I probably saw it) As for search terms, the ones that spring to mind are voip, SIP, H323, MGCP, pbx, DUNDI. YMMV. What kind of telephony - going to work for a telco, or setting up your own pbx somewhere?
