The outgoing caller-id is probably just the extension number, so the
provider is setting it to a default (usually the main billing number).  You
can set what Asterisk sends as the outbound Caller-ID in the outbound
context before the Dial statement.  Make sure your provider will honor what
you set, as many filter what you can send to only the DIDs they provide for
you.

Take a look here for more information on setting the caller-id in the
dialplan:
