RetryDial() — Attempts to place a call, and retries on failure
RetryDial(announce,sleep,loops,technology/resource[&Technology2/resource2...] [,timeout][,options][,URL])
Attempts to place a call. If no channel can be reached,
plays the file defined by announce, waiting
sleep seconds to retry the call. If the
specified number of attempts matches loops,
the call will continue with the next priority in the dialplan. If
loops is set to 0, the call will retry endlessly.
While waiting, a one-digit extension may be dialed. If that
extension exists in either the context defined in ${EXITCONTEXT} (if defined) or the current
one, the call will transfer to that extension immediately.
All arguments after loops are passed
directly to the Dial()
application.
