Unable to hear announcements

I have completed an asterisk/freepbx install on Debian 7 64 bit and have the following problem.

Asterisk 13
FreePBX 12

When I create an outbound route that is not functional, i.e. a BRI card with no services and dial a number that would use that service, all I get is silence followed by ring tone, then fast beeps.

The log shows that all circuits are busy now and please try again later are being played.

If i write a custom script in extensions_custom.conf I can hear the announcements.

Has anyone seen this problem or similar?

I can provide logs if necessary.

TIA

Ian
