Hi,<br><br>is there any way to route fax calls according to the call capability?<br><br>I mean .. if the fax call supports T.38 i'd like to route it to a T.38 capable gateway. All other fax calls (meaning inband) should be handled by FS/SpanDSP.<br>
Of course, I know that every fax call starts as a voice call and upon fax tone detection additional capabilities are being negotiated(T.38 or G711). Can it be done in early media, before the call is even answered?<br><br>
</blockquote><div>I don't claim to be an expert in all this, especially T.38, but if I understand correctly, in both cases the call needs to be answered first. I'm pretty sure that the sending fax machine won't start emitting the 1100Hz tone until the receiving end answers. Also, with T.38 doesn't the call have to come up and then T.38 gets negotiated? (I don't know, I have only read about it.)<br>

<br><br>So, here the goal is to have a T.38 capable GW handling T.38 calls while SpanDSP handling T.30...<br><br><br>Any chance to do that with FS?<br><br><br>
