[SR-Users] Issue with non static values for sleep in the Async module

[Will Ferrer]

Hi Daniel

Thanks very much for the response.

I tried this:

$var(buffer_duration) = $avp(buffer_duration);
async_route("WITHINDLG_DELAYED", "$var(buffer_duration)");

It worked! I guess it needed to be in quotes.

Thanks much as always.

Will
