Controlling it through the sip.conf peers is sufficient for us for this case (because this particular provider doesn't support T.38 at all), but I think it would be a good idea to add the option to enable/disable T.38 from the dialplan. If I recall correctly, that's how callweaver worked at the time.
In Asterisk trunk (soon to become Asterisk 1.10), there is an 'F' option to ReceiveFAX and SendFAX that forces audio mode FAX even if the channel is T.38 capable. That would do what you want. I posted a patch some time ago for Asterisk 1.8 to add the same ability, but it probably doesn't apply any more... the it's only a few lines though, it should be fairly easy to replicate in the Asterisk 1.8 version of res_fax.c
Also, we just checked it, and since for that provider, we have other codecs in higher priorities (like GSM, for example) than G.711, G.711 was not chosen as the only codec, so the fax transmission failed. We can not prioritize G.711 over the other codecs in the sip.conf, for the obvious reasons, so for this, we need to do it in the dialplan. How can we do it?
How are you going to determine that you need to force G.711 to be used? -- Kevin P.
