are going to be bringing in a PRI and routing all the DIDs from our existing

work…<o:p></o:p></SPAN></P>

are going to use Linksys ATAs (tested with a SPA2102) which will have the POTS
fax machines plugged into them, the SPA2102 connects to asterisk with SIP,
asterisk will then route the calls to t38modem (recent dev versions of it
support SIP and not only H.323), t38modem is basically just like IAXmodem
except its SIP and supports t38 termination. T38modem will again feed
hylafax, which will then route back to asterisk through IAXmodem and then up
the PRI.<o:p></o:p></SPAN></P>

certainly not a pretty solution… but we haven’t come up with anything else

Hylafax can possibly be bypassed and have t38modem talk directly to
IAXmodem.<o:p></o:p></SPAN></P>

[asterisk-users] T.38 fax solution, opinions?<o:p></o:p></SPAN></P></DIV>
<P class=MsoNormal><o:p> </o:p></P>
<P class=MsoNormal>Hi,<BR><BR>I'm putting together a fax solution for my
company that utilizes T.38. I wanted to throw out my plan and get some
feedback if anyone is doing something similar or sees a blatant problem with
it.<BR><BR>We're currently rolling out SPA-942 phones for the standard desk
phone with vanilla Asterisk 1.4.15 (just upgraded it today) on the back end.
Most calls for satellite offices are handled by VoIP providers (for voice
Vitelity inbound, Gafachi outbound). These satellite offices are using a T.38
fax DID from Gafachi, passed through the Asterisk server to a Linksys 3102 ATA
and then to a POTS fax machine. This all works well thus far. <BR><BR>Our HQ
has a full voice PRI, terminated on the Asterisk server with a TE120P.
Additionally, right now they have five fax lines totally separate from the PRI
that are used for POTS fax machines.<BR><BR>I'm thinking of porting those
numbers to the PRI and purchasing a TDM880B (comes with eight FXS modules) and
routing the fax DIDs to the 880 in Asterisk. Five of the ports would connect
into a Linksys 3102 that would speak T.38 to what would be our new fax
environment (Exchange 2007 Unified Messaging). That part isn't implemented
yet, but it shouldn't be a problem. Once it's implemented I'll probably
reroute the Gafachi T.38 fax DIDs to Exchange through Asterisk (with sipX in
there somewhere).<BR><BR>The part(s) I'm unsure about is the TDM880B. I
haven't used a FXS card with Asterisk, and I certainly haven't used a fax
machine on that FXS. Additionally, I'm not 100% sure the 3102 will talk
directly to Exchange UM yet, but that's something I can figure out myself
soon; I'm just not sure about spending the cash for a TDM880B without knowing
someone has thrown faxes through it from a PRI terminated on the same box from
a separate card. <BR><BR>Anyway, thoughts, criticisms, insults and stinging
barbs all welcome.<o:p></o:p></P></DIV></BLOCKQUOTE></BODY></HTML>
