You could force g711 inbound by using<br>
<br>
Set(SIP_CODEC=ulaw)<br>

In Asterisk trunk (soon to become Asterisk 1.10), there is an 'F' option<br>
to ReceiveFAX and SendFAX that forces audio mode FAX even if the channel<br>
is T.38 capable. That would do what you want. I posted a patch some time<br>
ago for Asterisk 1.8 to add the same ability, but it probably doesn't<br>
apply any more... the it's only a few lines though, it should be fairly<br>
easy to replicate in the Asterisk 1.8 version of res_fax.c<br>

How are you going to determine that you need to force G.711 to be used?<br>
