I just tried it. Looks to me that the answer is no.

When forcing G729 I get:
Got SIP response 480 "Temporarily unavailable" back from 147.135.0.128

With G726 the call "connects" but all you hear is the friendly voice saying 
"your call cannot be completed at this time". Changing it back to g711 makes 
it work again.

FYI, sip show channels shows:

Peer             User/ANR    Call ID      Seq (Tx/Rx)   Format  Duration
147.135.0.128    3604000000  5acd3e62478  00102/00000   G726    0:03
164.67.000.000   11          2f1743df-f5  00101/00102   ULAW    0:03
