You could also ask for experiences on the berofix mailing list. It's
mostly in Ge
If you are sending the fax out your PRI line then your PAP2T with
AstLinux should work just fine, so disregard my earlier response about
T.38 and VoIP providers. Use the G.711 codec, echo suppression and
echo canceler off.

If your VoIP provider is setup for T.38 then you may have an issue.
For in-bound faxes you are in control: If you don't allow T.38 then it
will stay with whatever codec you have negotiated. Which should be
g711. For out-bound faxes you are at the mercy of your VoIP provider's
setup. The rec
Hi Tom
Looks like the berofix supports the T.38 fax protocol, it would be worth
investigating ATA T.38 support, I'm no expert but maybe worth investigating
more(I know g729 doesn't like to play, and even with the higher bit rate
codecs, you can have mixed results :-( )
URL's worth a read

Hi Tom,
what I've heard, is to best use an ISDN Terminal adapter like the TA33

Probably, because you are then less susceptible to the variables of SIP
trunking. Given you have some PAP2T's I would suggest you just test it.
Set codec to ulaw or alaw, turn off echo cancel and set jitter buffer to
low.
Good luck.

As always, I needed to be clearer in my description. Our only trunking is
ISDN PRI. We are only using SIP/IAX internally. So, would a PAP2T (various
of which I currently use for voice) work well as the bridge between our
internal analogue fax and our internal Astlinux box, sending and receiving
fax
I should add that the PAP2T I have is one that I got through Nextalarm.com
which is customized to support alarm/security system monitoring over the
internet (VoIP). The ATA is customized to connect one of the analog lines
into their systems, the other line is available to configure for my own use

The answer is "it depends." I have had success with a fax machine connected
to a linksys PAP2T ATA and routing through vitelity as the SIP trunk
provider (with Astlinux in-between). I have had complete failure with an
older Linksys/Sipura SPA-2002 and the same SIP trunk.
I have both a PAP2T and

With an uncustomized 0.7.2 (1.4) on a net5501 with a berofix PRI, what is
the easiest way to attach an analogue fax which currently uses one DDI on
the UK PRI? Will an ATA work?
Thanks
