missing phones from English?

[awhillas]

From my understanding there should be at least one phone for each phoneme in English of which there are supposed ot be 44 phonemes so presumably at least 44 phones. When I do gruut-ipa print --language en-gb I get 33 phones (and 36 for en-us)? The phoneme data files have 42 and 40 phonemes respectively?

Also, the phones command doesn't seem to handle dipthong vowels at all, splitting them up into two phones?

What am I missing here?
