I've managed to resolve the issue.

I noticed that whenever the call was successful, the media endpoints had the
same IP address as the SIP signalling endpoints, and whenever the call was not
successful, the endpoints were different.  I found that the nf_conntrack_sip
module has a parameter called 'sip_direct_media' that by default only allows
the signalling and media endpoints to have the same IP address.  On specifying
the option to remove this strict requirement, the problem disappeared and calls
became successful.

So the conntrack SIP module is working as designed and there is no bug. 
Apologise for the false alarm.
