Well, that's weird and probably a bug....

You offer (ulaw|g729|gsm) to them
and they pick alaw !

But you aren't actually using the IAX friend (peer) entry for them

Try:

[magrathea]
type=peer
host=iax3.magrathea-telecom.co.uk
username=thinguser
secret=thingsecret
disallow=all
allow=alaw
notransfer=yes

and change your dialplan to say:

Dial(IAX2/magrathea/${EXTEN})
