[Spce-user] T.38 <-> G.711 Transcoding

Is it possible for C5 CE (using rtpengine) to transcode between T.38
(a-leg) and G.711 (b-leg) ?
I've tried setting it up, but I can't figure out how to set the media
settings facing each leg (t38_force, t38_decode. etc.).
Here's the scenario ...
A-leg (T.38): Analog Telephone Adapter
B-leg (G.711): Carrier SIP Trunk
On the A-leg, it would be good if we could force C5 CE to Re-INVITE T.38 to
the ATA immediately at the start of the call. But not sure if C5 CE can do
the Re-INVITE or if it must come from the ATA?
On the B-leg, it would be good if we could stay on G.711 and refuse any
T.38 Re-INVITES that may come in from the carrier?
