T.38 is good but is a pain.<br>
i strongly suggest you to pass it through PCMU (G.711U) codec, sunse
you're willing to use E1 boards<br>
no transcoding required and less ressources<br>
thank you<br>

<div>I am trying to implement a workable fax solution between two
FreeSwitch servers. This is what I had in mind so far:</div>
<div><br>
<div>T1 PRI <--> Sangoma A102 <--> FreeSwitch (host)
<--> T.38 SIP (internet) <--> FreeSwitch (remote)
<--> Sangoma B600D <--> FAX machine</div>
</div>
<div><br>
</div>
<div>I am assuming here that the T.38 protocol between FreeSwitch
servers will ensure that the data transfers between the two sites
successfully. Would this actually be a two step process, where one
server receives the fax (say, from the PRI) on one call, then sends to
the second server, and the second server initiates a second call to the
fax machine?</div>
<div><br>
</div>
<div>The object here is to successfully pass faxes using SIP. Is
there a better way to handle this?</div>
<div><br>
</div>
<div>Thanks in advance,</div>
<div>Chris </div>
