Hello,
a new module is now in GIT master branch, named async.
Its purpose is to provide asynchronous SIP request processing using
t_suspend()/t_continue() mechanism from tm module. While the tm module
had it for quite some time, it was not available for usage in
configuration file.
There are two functions implemented by now:
- async_route(routename, interval) - execute asynchronously a route
block after a time interval
- aync_sleep(interval) - sleep asynchronously for a time interval and
then resume SIP request processing
See the readme for more details:
http://kamailio.org/docs/modules/devel/modules/async.html
Cheers,
Daniel

Seems kind of sexy.
Do you have a good example of usage?

Delayed forwarding of requests or delayed
replying - like 100 trying, 180 ringing immediately when invite comes in, then
async_route() to reply 408 timeout after 20 sec when you run out of gw capacity :-).
All without blocking main sip workers.
For SIP MESSAGE to SMS you can use the mechanism just to switch to other pool of workers
in case SMS gatewaying is blocking - although this can be achieved as well with mqueue and
rtimer modules if you don't need the full sip request in special workers.
Just some thoughts ...
Hopefully the module will help others to contribute more functions that will work
asynchronously. My todo has some more ideas here as well, just that is as long as Madrid -
Berlin, so may not get in that soon :-)
Enjoy the cold Saharian daylight temperatures,
Daniel
