[asterisk-users] IAXModem or T38Modem?

[Mike Diehl]

Hi all,

[Ксения Юрьевна Блащук]

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

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,

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.

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.)

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.
