 |
|
Hi all,
I'm installing Hylafax on my Asterisk system. From what I've read, I can either use IAXModem or T38Modem to provide the virtual fax device. So at the risk of starting a religious war, which one should I use?
I don't mind running IAX if I have to. I want as much flexibility and stability as I can get.
So, what are your recommendations?
Mike. |

Personally I use spandsp + res_fax (res_fax.so, res_fax_spandsp.so) and SendFAX/ReceiveFAX applications.

I have to use both. IAXModem is fine for sending but receives garbage,
and T38Modem is fine for receiving but treats all outgoing calls as
busy.

It depends on Your environment and Your asterisk version. If Your
connection to the PSTN is via ISDN (eg. channel via DAHDI or CAPI), You
should use IAXmodem. The fax is transferred on the audio layer and there
is no need to translate it into T.38. If Your connection is via some
VoIP Provider using T.38 or via a Mediagateway like BeroFix, You should
use T38Modem.
Newer versions of asterisk have additional features regarding T.38
(AFAIK). In this case there may be no need for any of the modems.
HTH,
Karsten

We use IAXModem-1.2.0 built from source and packaged as an rpm using
mock/rpmbuild together with Hylafax+-5.5.3 from epel. Since April 2013 this
combination has been running two dedicated POTS lines through a TDM800-p8 on
our Atom CentOS-6.3 based Asterisk-11.7.0 (current version) box without any
reported difficulties (once I sorted out the upstart stanzas).
As this is the only combination I have experience with it is the only one I
can recommend. But it has proven very reliable so far as I am aware and I
would be made aware pretty quickly if it was not.

we are using T38modem, it was a long way to get it stable, but finally
it works quite good with 10 parallel running T38modems.
But your carrier has to support T38, when we began to evaluate this some
years ago, this was not true for all.

Would you share the provider you are using? I have had almost zero luck
so far.

What country are you in? Every carrier we’ve tried in the UK supported T38 without problem (so far.. I expect there is a few that don’t). Not sure I can name specific carriers as this is the non-commercial list though.

Sorry - should have mentioned USA. I say "almost" zero luck, because I
have managed to get a few faxes out with a handful of providers tested,
but none consistently. If anyone is very happy with their T.38 provider,
please email me off list.
I got the spam message. At least she is cute.
Cheers,
j

I would not say "happy", since there is no happiness in a world with T.38, but Level 3 supports T.38. Level 3 is wholesale only as far as I know.
Vitelity has some fax service stuff too.

In my experience iaxmodem + Hylafax is very stable and work in my setups
fine.
But in these setups I either use ISDN uplinks or SIP trunks with low RTT
and jitter (highspeed links to the service provider, no WAN links).
Thus, T38 is in my setups not necessary.
regards
Klaus

I wouldn't mind if someone posted on the list a known working provider
with the proper configuration to use T.38. In my case I don't consider
it an issue with the provider because they sent the proper T.38 Invite,
but Asterisk IMO does not know how to handle it.

Are you using a single credential-tuple with the provider?
If the provider supports T.38 and if you can separate out fax lines,
there is no need to stick asterisk between them and t38modem. Just have
t38modem access the provider directly. Hylafax will handle the rest.
(Look for things like sub-account, peer and/or trunk configs.)
