+1 Bryant - by using the Local/Context you are introducing some overhead to
the process, but eliminating the dependence on DAHDI timing (not that
there's anything wrong with that per se, but you can't control the Space
Shuttle with a Bearcat Scanner (or can you?) ).

If you dial to a Local/Context and use your time limits on that and then do
your dial to your DAHDI device inside that context does that have any effect
on the time limits working. We have used time limits with Local/Context
dials and had them work with out any known issues.
Thanks

Please elaborate on your "flavor" of DAHDI and LIBPRI and what type of DAHDI
service you are using (PSTN, T1, etc). Speaking from a POTS line point of
view, there can easily be a 7-10 second delay in the processing of DAHDI
information (which would make your 1347 second call within tolerance).

Hi,
We're trying to time-limit some calls by specifying L(x:y:z) as an option to
the Dial command.
If we set the limit to a fairly short duration (eg 120 seconds) then
Asterisk seems to issue the hangup at about the right time.
However, for longish calls we're seeing quite a bit of overspill. For
example we tried to limit one to 1338 seconds but Asterisk didn't hang up
until 1384 seconds after the call was answered.
Also, the error is not always consistent - a second test call also limited
to 1338 seconds was hung up by Asterisk after 1347 seconds.
We saw this problem with Asterisk 1.6 but we've now tried on Asterisk
1.8.6.0 and are having the same problem.
Here's a log from the Asterisk 1.8.6.0 box for the test call that should
have been limited to 1338 seconds but was actually ended after 1384 seconds.
The server wasn't carrying any other calls at the time or doing anything
else so the load would have been very low.
