[Freeswitch-users] Writing FS apps via mod event socket + node.js

[Alex Lake]

Thanks - I've seen this, but the examples are not at all representative 
of the sort of thing I want to be doing with freeswitch (which is mostly 
about handling calls in accordance with a dialplan, but with some 
complex stuff involving multi-legs). It makes me think I must be barking 
up the wrong tree....

These examples seem very much web-linked.

Let's consider an example:

If one wanted a very simple dynamic call mini-conference service - call 
comes in from a PSTN gateway, the code hits an HTML server (eg. using 
RESTful protocols) which returns a comma-separated list of destinations 
and then the system bridges to these destinations. Perhaps plays them a 
little fanfare and then links them all together in a conference.

I could do that with simple dialplan and Lua easy enough, but how would 
I do it in node.js?
