Hi Marco,
this is not an asterisk issue, it is a UNIX/Linux-issue.
If you overwrite a file, asterisk of course plays the data it reads from
the (at that moment overwritten) file.
I would suggest to delete the file and then write the updated file. On
UNIX if you delete an opened file, the program reading from the deleted
file still has access to it, until it closes the file.
The problem with this is, that you have a race condition: If asterisk
tries to read the file at that moment, where you just deleted the file
and did not yet create a new one, the caller would hear nothing.
Probably a thing which can be fixed in your dialplan by re-reading the
file if it is empty.
HTH,
Christoph

Hello everybody,
does anybody know how to handle the following problem?
I update some gsm audio files every 10 minutes, by rewriting directly
on them.
I've noticed that if the file is being played by asterisk exactly in
the moment when I rewrite onto it, who is calling hears a small "jump"
and then it is the updated file that starts being played, starting
from about the same position of the old one.
(i.e. if the update arrives after 10 seconds of playing on the old
file, the updated file starts after the jump about at its 10 second
position).
I would prefer to end up with the old file without changing the
current conversation.
Maybe a parameter handle this?
Otherwise the only way that I see is to give a different name to each
file, then let asterisk read the most up-to-date. But it would be not
as easy as it is now.
For information, I use Asterisk 1.2.6 on Linux CentOS. I pay a SIP
Gateway to have a geographical number that points to my asterisk
(sorry if I do not use the correct terms).
Thanks a lot!
Cheers,
Marco
