The first parameter to app dial is the ring timeout, so yes it is as you
mentioned above. So speciy the max time as S(n) where n is the max number of
seconds the call should last.

So I guess the line should be

snprintf(dialstr, 256,
"SIP/number at host.com|%lu|S(%??)",ringtimeout,timeout);

I am not a C programmer so probably got the syntax totally wrong, however
hope it makes sense to you.

When I did my app, I did it as a Pascal application running as an AGI
script. There are lots of issues to be considered, and I am happy to have
further discussions on this topic. Also are you in the position to share
your code ?
