Indeed I am going for pure voip and trying to figure out how to<br>
implement t.38, as you suggest.<br>

Like what? I'm not familiar with this tech, I googled around a bit but<br>
didn't come up with much. I think I just don't know the lingo yet. :<br>

So basically what you're saying is that to do this (convert the analog<br>
to t.38) myself I would still need to have analog coming into my<br>
asterisk server (which makes sense, but doesn't help me avoid paying<br>
for "normal" phone lines)... Sounds to me like in this situation t.38<br>
would be purely for getting faxes around on my own asterisk(s) if that<br>
became necessary.</blockquote><div><br>What I meant is that, instead of using a separate box for connecting your own fax machine, you could use an analog board such as :<br><br>ITSP ----<xDSL> --- router ---<LAN> ---Asterisk 1.6 w/ FXS board === fax machine<br>
<br>Just as previous 1.4 setup, you wouldn't need a separate analog line for faxing.<br>But judging from your question, I would add that it's not common to find an ITSP able to deliver T.38 services (inbound or outbound).<br>
And if you want to be able to switch from one provider to another, or simply for simplicity, it's recommended practice to dedicate an analog line to faxing.<br><br>You setup becomes :<br><br>ITSP ----<xDSL> --- router ---<LAN> ---Asterisk 1.6 w/ FXO-FXS board === fax machine<br>
||<br>PSTN ===============================<br>
<br>I should also add that if you're having a single fax machine, maybe you should just connect it to an analog line.<br><br><br><br></div><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
<br>
<br>
Which leads me to my other question again, is there some sort of<br>
internet service that will do the analog to t.38 conversion for me and<br>
then pass the t.38 on to my asterisk server?</blockquote><div> </div><div>In your previous question you said "pure VoIP" which implied you had found such provider. <br>Here you will some answers :<br><a href="http://www.voip-info.org/wiki/view/VOIP+Service+Providers+T.38">http://www.voip-info.org/wiki/view/VOIP+Service+Providers+T.38</a><br>

Andrew you mentioned something about sip providers that support t.38?<br>
When you say support, do you mean that they have passthrough turned<br>
on, or they will actually do an analog t.30 to t.38 conversion for<br>
you? That may be what I'm after... If you, or anyone else, know of a<br>
provider that does this could you point me in the right direction?<br>
<br>
Thank you all for your thoughts.<br>
