Infact turns out to be user error, when installing the codecs followed
the Digium insructions implicitly, which downloaded the codec optimised
for a P4, while the system running was 686 architechture.

We installed a 686 codec and suddenly everything sprung to life ;)

However though it works, codec negotiation is still weird, using a
SPA-3K with g.729a set to the preferred codec seems to ONLY use that.
While a Cisco phone (though having g.729 inbuilt) tends to negotiate say
alaw on a local LAN segment talking to the Asterisk box - while an IAX
call elsewhere is using g.729 (i.e. reguires translation). It doesn't
seem to do end to end negotiation.
