I have tested this with current versions... ok so unlike many others... I find G711 gives better faxing than T.38 ( for many reasons... but mainly because all my network is fibre and I control a lot of it myself ). I have one carrier that that insists on doing fax tone detection in their SBC. the call comes in G711... they detect fax tones then re-invite T.38. I want to knock the T.38 back, but cant.. if I disable T.38 we get the 100 Trying... then nothing further. only way I can inter-op is to use t38.

what is the entire call flow? And what rev are you using... fax_enable_t38_request=true will make us send a re-invite.

yup I saw that.... and I thought I already knew the answer to that question. but im still yet to find a way to specifically knock back a T38 re-invite :(
( FS does this 100 trying... but nothing further .. )
