Asterisk not doing anything when run as a service

Hi fellows.

I encounter a strange problem with asterisk on my ubuntu server.

When I start asterisk via “/etc/init.d/asterisk start” script, asterisk seems to loose the extensions.conf because I am not able to dial in or out anymore.
(Logfile says that my phones are “now reachable” but can not find any extensions on incoming or outgoing calls)

Then I tried to start the server via “asterisk -cvvvvvvvvv” AND everything started working fine.

Do you know this behavior?
Is there a way of finding out the path to the config files used while the server is running?

Thank in advance.

I’m not too familiar with the ubuntu way, but maybe locate extensions.conf would shed some light
